Rtools is not an R package. Its a collection of UNIX-like windows
software and other software such as perl. It is used by R package
authors to supply the additional tools that are needed on Windows to
build R packages from source. If you don't need to build R packages
(that is you are content to use the Windows binaries) then you don't
need Rtools. Also I don't think this or my other comments have
anything to do with your problem. My comments were primarily in
response to Spencer's comments.
Regarding your question about gdata,
1. if gdata did not get installed then just do this from within R:
install.packages("gdata")
(or use the Packages | Install Package(s) menu to accomplish same).
If that still does not result in gdata being installed then try a
different mirror.
2. there is no gdata() function in the gdata package so your line
which tries to call it would be expected to return an error even if
gdata were present.
