Metagenomics Analysis Tools: the matR package

The matR package and manual (HTML; pdf) are available on CRAN; see “Installation” at the bottom of this page to get started. Just below, some extended tutorials are available in HTML and pdf versions. Also, with matR loaded you can execute these in your R session, for example with:

step.through(file="http://mg-rast.github.io/matR/analysis-in-a-nutshell.R")

In the same way, “Other scripts” (below) can be viewed here or executed locally. The “Extensions” section lists add-ons to the CRAN version of the package. There’s no reason to step through them line by line, but the extra functionality they provide can be introduced to your R session, for example with:

source("file="http://mg-rast.github.io/matR/local-workbench.R")

Please credit this software if it assists your work. R proposes a standard form for package citation shown by:

citation('matR')

Installation

Make sure to have a current version of the R language. Then open an R session and install with:

Go through the several prompts following dependencies(). Once installed, the package must be loaded during every session with: library(matR).
