The function vignette("RNAseqNet") will find the short
RNAseqNet vignette that describes how to obtain the RNAseqNet User's Guide.
The User's Guide is not itself a true vignette because it is not
automatically generated during the package build process. However, the
location of the Rmarkdown source is returned by the function if
html = FALSE.
If the operating system is not Windows, then the HTML viewer used is that
given by Sys.getenv("R_BROWSER"). The HTML viewer can be changed using
Sys.setenv(R_BROWSER = ).
