limmaUsersGuide {limma} | R Documentation

## View Limma User's Guide

### Description

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

### Usage

    limmaUsersGuide(view=TRUE)

### Arguments

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

### Details

The function `vignette("limma")` will find the short limma Vignette which describes how to obtain the Limma 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=)`.

This function is used by drop-down Vignettes menu when the Rgui interface for Windows is used.

### Value

Character string giving the file location.
