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,

Thank you Peter. I am really new to this. The spreadsheet I am working with
has 12,379 rows with the first row consisting of the variable names and
12,378 rows of data. There are seven columns, and the 7th column is the only
one with numerical data ("Results").
I need to match up the variable Re

I am so happy about learning how to read in multiple Excel files, that I have
to try and make another improvement. I know what I have been doing is
clumsy, but it works. Hopefully, someone can suggest a more elegant
solution. As a novice, I have been using MS-Word and mail merge to write my
code.

Dear list:
I have a problem using the subset function:
dat<- data.frame(treatment=c("A", "B", "A", "C", "C", "D", "A", "D",
"C", "D"), response=rnorm(10))
I am interested in treatments "A", "B" and "D"
vec<- c("A", "B", "D")
But I can only obtain what I want with:
subset(dat, treatment=="A" | t
10 matches
