Several people have indicated how to do this, but I encourage you to be
sure you really need to do it. Many things can be made to work the same
way on all OSs, and packages are much easier to maintain if you do not
have several variants. You might consider posting a few example of
where you find this necessary, and ask if there is an OS independent way
to do it.

Would I be better off just to build two separate packages, please?
If just one is needed, how could I determine which system is running
in order to use the correct command, please?
Thanks in advance,
Erin

If just one is needed, how could I determine which system is running in order to use the correct command, please? You will find it much easier to build just one package. You can use .Platform or (for more detail) Sys.info() to find out what kind of system you're running on. Remember that R doesn't just run on Linux and Windows: there's also MacOSX, and other Unix and Unix-like systems (Solaris, etc.).

There is the version (a list) variable:
version
# platform i486-pc-linux-gnu
# arch i486
# os linux-gnu
# system i486, linux-gnu
# status Patched
# major 2
# minor 4.0
# year 2006
# month 11
# day25
# svn rev39997
# language R
from which you can extract the os component:
version$os
# [1] linux-gnu
I don;t know what this says on a Windows system,
but it surely won't mention Linux!
So testing this wil enable you to set a flag, e.g.
Linux-ifelse(length(grep(linux,version$os))0, TRUE, FALSE)
if(Linux){window-function(...) X11(...)} else
{window-function(...) windows(...)}
Hoping this helps,
Ted.
