Linux and Windows use different end-of-line delimiters, but R doesn't care
about that.
If the code uses the system( ) call to directly invoke an OS command, then
that code is almost certainly tied down to one operating system. For
example, system("date") works fine on Linux, but doesn't on Windows.
Well, not on some Windows systems. On mine, I get

This is because I have the date command installed as part of the R
tools. (Date is also available in a number of other toolkits that make
Windows shells more Unix-like.)
So your point is valid that code written to use system functions on
Linux is unlikely to work in a plain out of the box Windows system, but
it's often not hard to get it to run.
