edgeRUsersGuide: View edgeR User's Guide

In edgeR: Empirical Analysis of Digital Gene Expression Data in R

Description

Finds the location of the edgeR User's Guide and optionally opens it.

Usage

edgeRUsersGuide(view=TRUE)

Arguments

view	logical, should the document be opened using the default PDF document reader?

Details

The function vignette("edgeR") will find the short edgeR Vignette which describes how to obtain the edgeR User's Guide. The User's Guide is not itself a true vignette because it is not automatically generated using Sweave during the package build process. This means that it cannot be found using vignette, hence the need for this special function.

If the operating system is other than Windows, then the PDF viewer used is that given by Sys.getenv("R_PDFVIEWER"). The PDF viewer can be changed using Sys.putenv(R_PDFVIEWER=).

Value

Character string giving the file location. If view=TRUE, the PDF document reader is started and the User's Guide is opened, as a side effect.
