[R] grid Graphics by Paul Murrell

[Simon Woodhead]

Dear All,

I've been trying to format a plot output using par() with mfrow, fin, 
mai, etc and basically it's proving to be a pain. I searched on google 
and found that Paul Murrell had written a grid Graphics program which 
seems perfect. However, when I try and use say viewport() I just get a 
function not found error. Can someone tell me what I'm doing wrong please?

Thank-you

Simon
