In follow up to Andrew and Prof Ripley on your second question, one
thought comes to mind on the file load issue. That is to be sure that
you have properly specified the file's pathname when loading it.
I am presuming that you are under Windows.
Be sure to use either Linux/Unix-like pathnames using the "/" separator
or use a Windows-like double "\\" in the path. Also be sure to use
double quotes around the full file/pathname.
Thus, within Rgui if you use source(), use something like:
If you are using Rterm from a Windows command line use something like:
Rterm.exe --no-restore --no-save < "C:/My Documents/file.s" > R.out
Rterm.exe --no-restore --no-save < "C:\\My Documents\\file.s" > R.out
In both cases, of course adjust the file/pathname accordingly. On the
command line, spaces in the pathname as with "My Documents" will cause
problems since the text on either side of the blanks will be treated as
separate command line arguments, not as a single filename. Thus
surrounding the full path/filename with double quotes will help.
BTW, this is covered in the R Windows FAQ at
2.13 R can't find my file, but I know it is there!
Hope that might help,
