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"))
