It does something, ... but no enough.
The backslashes are no longer being enterpreted as
escape codes, but the forwardslashes don't appear to
be instered.
The error mesage I get is 
cannot open file `C:workingcricketstrip_odi.r' 
the file name should be C:/working/cricket/strip_odi.r
I changed a couple of obvious tinkers, namely
change "load S file"  to "load R file", and 
changing "[\\]" to "[\]".

any further ideas?  
Thanks
