biobroom: Tidying up computational biology

This package contains methods for converting standard objects constructed by bioinformatics packages, especially those in Bioconductor, and converting them to tidy data. It thus serves as a complement to the broom package, and follows the same the tidy/augment/glance division of tidying methods. Tidying data makes it easy to recombine, reshape and visualize bioinformatics analyses.

biobroom implements tidying methods for both S3 and S4 classes. Objects that can be tidied include

  • ExpressionSet objects
  • MSnSet objects
  • per-gene differential expression tests from limma, edgeR, and DESeq2
  • qvalue multiple hypothesis testing objects

Installation

First install the package's requirements (requires devtools):

source("http://bioconductor.org/biocLite.R")
biocLite(c("Biobase", "limma", "edgeR", "DESeq2", "GenomicRanges", "MSnbase"))
devtools::install_github("dgrtwo/broom")

Then the package can be installed with

devtools::install_github("dgrtwo/biobroom")

Find out more about the provided methods with:

library(biobroom)
?edgeR_tidiers
?DESeq2_tidiers
?limma_tidiers
?ExpressionSet_tidiers
?MSnSet_tidiers

Note on returned values

All biobroom tidy and augment methods, since they tend to be large data frames, return a tbl_df by default (this prevents them from printing many rows at once, while still acting like a traditional data.frame). To change this to a data.frame or data.table, you can set the biobroom.return option:

options(biobroom.return = "data.frame")
options(biobroom.return = "data.table")
