I am having difficulty installing packages. For example, here I have tried to
install "gplots" but to no avail.

install.packages()

** building package indices ...
* DONE (gplots)

The downloaded packages are in
        /tmp/Rtmp5NZLyb/downloaded_packages
?plotCI
No documentation for 'plotCI' in specified packages and libraries:
you could try 'help.search("plotCI")'


Of course not.

You have to ***load*** the package, e.g.

        library(gplots)

before you try to use it.  Psigh.
