veccompare: Automatically Generate All n-Wise Set Comparisons on Vectors

Description

The veccompare package contains functions for automating set operations. Given a named list of 5 vectors, for example, veccompare can calculate all 2-, 3-, 4-, and 5-way comparisons between those vectors, recording information for each comparison about the set "union" (combined elements), "intersection" (overlap / shared elements), and compliments (which elements are unique to each vector involved in the comparison).

Details

The veccompare package contains functions for automating set operations (i.e., comparisons of overlap) between multiple vectors.

The package also contains a function for automating reporting in RMarkdown, by generating markdown output for easy analysis, as well as an RMarkdown template for use with RStudio.

The primary function from veccompare is compare.vectors. Complementarily, compare.vectors.and.return.text.analysis.of.overlap will call compare.vectors and generate Markdown-style output from it (for example, for use within an RMarkdown file).

An RMarkdown template illustrating several of veccompare's features can be used from within RStudio by clicking File -> New File -> R Markdown... -> From Template -> Veccompare Overlap Report.

veccompare also provides a function, summarize.two.way.comparisons.percentage.overlap, that can create correlation-plot-style images and network graphs for all two-way comparisons between vectors. This function is also demonstrated in the Veccompare Overlap Report described above.

compare.vectors(named_list_of_vectors_to_compare,
  degrees_of_comparison_to_include = NULL, draw_venn_diagrams = FALSE,
  vector_colors_for_venn_diagrams = NULL, save_venn_diagram_files = FALSE,
  location_for_venn_diagram_files = "", prefix_for_venn_diagram_files = "",

  saved_venn_diagram_height = 6, viewport_npc_width_height_for_images = 1,
  suppress_messages = FALSE)

Arguments

`named_list_of_vectors_to_compare`	A named list of vectors to compare (see, for example, `example.vectors.list`). Duplicate values in a given vector will only be counted once (for example, c("a", "a", "b", "c") will be treated identically to c("a", "b", "c").
`degrees_of_comparison_to_include`	A number or vector of numbers of which degrees of comparison to print (for example, 'c(2, 5)' would print only 2- and 5-way vector comparisons).
`draw_venn_diagrams`	A logical (TRUE/FALSE) indicator whether to draw Venn diagrams for all 2- through 5-way comparisons of vectors.
`vector_colors_for_venn_diagrams`	An optional vector of color names for Venn diagrams (if `draw_venn_diagrams` is `TRUE`). Color names are applied to the named vectors in `named_list_of_vectors_to_compare` in their order in `named_list_of_vectors_to_compare`. If this is blank, a random color will be selected for each vector. Either way, each vector will have a consistent color across the Venn diagrams in which it appears.
`save_venn_diagram_files`	A logical (TRUE/FALSE) indicator whether to save Venn diagrams as PNG files.
`location_for_venn_diagram_files`	An optional string giving a directory into which to save Venn diagram PNG files (if `save_venn_diagram_files` is `TRUE`). This location must already exist on the filesystem.
`prefix_for_venn_diagram_files`	An optional string giving a prefix to prepend to saved Venn diagram PNG files (if `save_venn_diagram_files` is `TRUE`).
`saved_venn_diagram_resolution_ppi`	An optional number giving a resolution (PPI) for saved Venn diagrams (if `save_venn_diagram_files` is `TRUE`).
`saved_venn_diagram_dimension_units`	An optional string giving units for specifying `saved_venn_diagram_width` and `saved_venn_diagram_height` (if `save_venn_diagram_files` is `TRUE`). Can be `px` (pixels), `in` (inches, the default), `cm`, or `mm`.
`saved_venn_diagram_width`	The width (in `saved_venn_diagram_dimension_units` units) for saved Venn diagrams (if `save_venn_diagram_files` is `TRUE`).
`saved_venn_diagram_height`	The height (in `saved_venn_diagram_dimension_units` units) for saved Venn diagrams (if `save_venn_diagram_files` is `TRUE`).
`viewport_npc_width_height_for_images`	The scale at which to print an image. If the image is cut off at its edges, for example, this can be set lower than 1.0.
`suppress_messages`	A logical (TRUE/FALSE) indicator whether to suppress messages. Even if this is `TRUE`, warnings will still be printed.

Value

A list, with one object for each comparison of vectors. The list contains the following elements:

elements_involved: The vector names involved in the comparison.
union_of_elements: A vector of all (deduplicated) items involved in the comparison, across all of the vectors.
overlap_of_elements: A vector of the deduplicated elements that occurred in all of the compared vectors.
elements_unique_to_first_element: This element will have a sub-element named for each vector being compared (i.e., for each of the names in $elements_involved). The (deduplicated) items that were unique to that vector (i.e., not overlapping with any other vector in the comparison).
venn_diagram: If save_venn_diagram_files is TRUE, and the comparison is of 2 through 5 vectors, a Venn diagram object produced using the VennDiagram package. This diagram can be rendered using render.venn.diagram.

To compile this list object into a Markdown report, use compare.vectors.and.return.text.analysis.of.overlap. For an example of this usage, see the Veccompare Overlap Report RMarkdown template for RStudio that is installed as part of the veccompare package.

veccompare::extract.compared.vectors(
  example,
  vector_names = c("vector_a", "vector_c"),
  only_match_vector_names = TRUE
)

# To get all elements that did a two-way comparison:

Details

Use of this function is illustrated with the Veccompare Overlap Report RMarkdown template for RStudio that is installed as part of the veccompare package.

Value

A string of Markdown (and Venn diagrams, if draw_venn_diagrams is TRUE).

If cat_immediately is TRUE, nothing is returned by the function; rather, the output Markdown is printed immediately (for example, as part of a Knitted RMarkdown document, or to the console).

If cat_immediately is FALSE, the output can be saved to an object (as in the example below). This object can then be printed using cat().

NOTE WELL: If cat_immediately is FALSE, the output should be saved to an object. If it is not, R will give an error message when printing to the console, because of unescaped special characters (which work correctly when cat() is used).

Examples

example <- compare.vectors.and.return.text.analysis.of.overlap(
    veccompare::example.vectors.list,
    cat_immediately = FALSE,
    draw_venn_diagrams = FALSE
)
cat(example)
example <- compare.vectors.and.return.text.analysis.of.overlap(
    veccompare::example.vectors.list,
    cat_immediately = FALSE,
    draw_venn_diagrams = FALSE
)
cat(example)

Extract elements from the output of `compare.vectors`

Description

Straightforwardly extract particular elements from the output of compare.vectors.

Usage

extract.compared.vectors(output_from_compare.vectors, vector_names = NULL,
  only_match_vector_names = FALSE, degrees_of_comparison = NULL,
  elements_of_output = NULL)
extract.compared.vectors(output_from_compare.vectors, vector_names = NULL,

Summarize Percentage Overlap for Two-Way Comparisons between Vectors

Description

Summarize Percentage Overlap for Two-Way Comparisons between Vectors

Usage


  summarize.two.way.comparisons.percentage.overlap(named_list_of_vectors_to_compare,
  output_type = "table", melt_table = FALSE, network_graph_minimum = 0,
  margins_for_plot = NULL)
summarize.two.way.comparisons.percentage.overlap(named_list_of_vectors_to_compare,
  output_type = "table", melt_table = FALSE, network_graph_minimum = 0,
  margins_for_plot = NULL)

Arguments

`named_list_of_vectors_to_compare`	A named list of vectors to compare (see, for example, `example.vectors.list`). Duplicate values in a given vector will only be counted once (for example, c("a", "a", "b", "c") will be treated identically to c("a", "b", "c").
`output_type`	Either `"table"`, `"matrix_plot"`, or `"network_graph"`. `"table"` will return a matrix showing percentage overlap between each pair of vectors. `"matrix_plot"` will plot this table, coloring it by the amount of overlap. `"network_graph"` will return a network graph image illustrating the overlap percentages between each pair of vectors.
`melt_table`	A logical (TRUE/FALSE) indicator, when `output_type` is `"table"`, whether to print the output in `melted` form (using the reshape2 package).
`network_graph_minimum`	`minimum` argument from `qgraph`, for when `output_type` is `"network_graph"`.
`margins_for_plot`	The margins for image output (if `output_type` is `matrix_plot` or `network_graph`). Specified as a vector of numbers, in the form `c(bottom, left, top, right)`. If `output_type` is `matrix_plot`, defaults to `c(2, 0, 1, 0)`; if `output_type` is `network_graph`, defaults to `c(3, 3, 3, 0.5)`.

Value

Either a matrix (if output is "table"), or an image (if output is "matrix_plot" or "network_graph"). If an image is printed, nothing is returned by the function; rather, the output is printed immediately.

If output is "table" and melt_table is FALSE, the output will be a matrix with nrow and ncol both equal to the number of vectors in named_list_of_vectors_to_compare. This table shows the decimal percentage overlap (e.g., "0.20" = 20%) between each combination of vectors. This table is intended to be read with row names first, in this form: "[row title] overlaps with [column title] [cell value] percent."

If output is "table" and melt_table is TRUE, the output will be a melted data.frame with three columns: Vector_Name, Overlaps_With, and Decimal_Percentage.

Examples

summarize.two.way.comparisons.percentage.overlap(veccompare::example.vectors.list)
summarize.two.way.comparisons.percentage.overlap(
	veccompare::example.vectors.list,
	output_type = "table",
	melt_table = TRUE
)

summarize.two.way.comparisons.percentage.overlap(
	veccompare::example.vectors.list,
	output_type = "matrix_plot" # You can also choose "network_graph"
)

summarize.two.way.comparisons.percentage.overlap(veccompare::example.vectors.list)
summarize.two.way.comparisons.percentage.overlap(
	veccompare::example.vectors.list,
	output_type = "table",
	melt_table = TRUE
)

summarize.two.way.comparisons.percentage.overlap(
	veccompare::example.vectors.list,
	output_type = "matrix_plot" # You can also choose "network_graph"
)

Arguments

`set_1`	A vector to be subtracted from.
`set_2`	A vector to subtract from `set_1`.
`suppress_messages`	A logical (TRUE/FALSE) indicator whether to suppress messages.

Value

A vector of the values of set_1 that are not present in set_2. Put differently, a vector resulting from subtracting set_2 from set_1.
