edgeRUsersGuide {edgeR} | R Documentation

## View edgeR User's Guide

### 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.
