Venn Compute

This R package is intended to compute specific elements in intersections of Venn diagram instead of plot.

• Custom reader of files to create list of character arrays (such requiered for this package and VennDiagram).
• Compute specific elements in intersections of Venn diagram in memory or write to files.
• Plot with VennDiagram.

How to install

You can install from GitHub as:

devtools::install_github("cosmoscalibur/venn.compute")

If an error about TAR executable is showed (common in Linux with Anaconda), you need to setup your TAR path.

Sys.setenv(TAR = "/bin/tar")

How to use

First, load the package.

library(venn.compute)

Read files

This is a custom reader to include multiple files and associate its custom names, returned a named list of character arrays (each element is an element line of the file).

sets <- read.lists_from_files(c(file.path("tests", "primes.txt"),
                                file.path("tests", "even.txt"),
                                file.path("tests", "fibo.txt")),
                              c("primes", "even", "fibo"))

Compute intersections and specific elements

Now you can compute specific elements of Venn diagram intersections.

venn.compute_specific(sets)

If you need to write sets in files, add an output path. Files are written using convention of join sets name with underscore.

venn.compute_specific(sets, output_dir = file.path("tests", "output"))

Plot Venn diagram

Finally, if you want to save plot, invoke this function with the same arguments as before.

venn.compute_plot(sets, output_dir = file.path("tests", "output"))
