Set PATH Variable

This section helps you to set up the PATH environmental variable in Windows. You need to add the full path of the directory to the PATH variable. Typically this full path looks something like C: $\backslash$bin. Your PATH should look something like:

C:\bin;C:\MinGW\bin;C:\Perl\bin\;C:\Tcl\bin;
C:\texmf\miktex\bin;

Where C: $\backslash$bin is the directory (you may change the name if you wish) you unzipped the tools bundled by The R Core Team, this should appear in front of your PATH. You should add other appropriate paths to suit your needs. For example, if you want to build the compiled HTML help files, then you need to add hhc.exe to your path. If you have other paths in your PATH, simply append the paths at the end. Do NOT, unless you know what you are doing, delete any paths that already appeared in your PATH.
