Hi Peter,
Thanks again for showing me how to do this. This will save me hours of
tedious work, and I can't believe how quickly R reads in and processes my
data. It was taking about 40 minutes when I used Word's mail merge for this.
When I first switched from Excel to R, R was so much faster than
Thank you very much Peter. I'm off until Monday, but now I have an
interesting project to think about over the weekend. It looks pretty simple,
and it sure will beat over 2,000 pages of code to cut and paste.
Thanks again,

one with numerical data ("Results").
I need to match up the variable Re

I'm not sure exactly what you wish to do, but it would seem you could
create a character vector (myVars) containing all your merge field names
and then use a for() loop. Something like:
for (myV in myVars)
{
x116 <- subset(napt, Analysis_Soil %in% myV)
if (nrow(x116) > 8)
{
Thank you Christos and Jim:
That is precisely what I was after.
