I just wanted to say, somewhat belatedly, a huge thank you to all those who
answered my question. I hope I have got all of you::
Thanks to Ruud, Jonathan, James, Martin, Andrew and Dennis.
Basically the solution and noted by these helpful people is to use infile
thereby creating an infile with php (using simple file io) calling R from
the command line with infile and writing the results to and output file
which can then be opened by PHP later.
The batch file call would be something like (from Ruud)::
path_to_R\bin\Rterm.exe --no-restore --no-save < %1 > %1.out 2>&1
And away I go.
Again thank you all :-)
