Hello all,
After some months doing ok with R, I am embarrassed that I have to make
this my first posting to the help list. I am trying to run the
following (actually in a loop but shortened for the post):
risk.factors <- c("file$A", "file$B",
"file$C", "file$D", "file$E")
table(paste(risk.factors[1]))
but run into problems with the table (paste...) line as I get the
following output:
> table(paste(risk.factors[1]))
file$A
1
I think it's a problem with paste including " " around the file
name but
cannot get around it. Apologies for the simple nature of this question
and thanks to anyone who can take a moment to help.
David.

Try this:
riskFactors <- c("A", "B", "C")
table(file[[riskFactor[1]]])
in a loop
for (i in riskFactor) table(file[[riskFactor[i]]])

What is the problem you are trying to solve?

I have to say it is not clear at all what you expected. risk.factors [1] is the character vector "file$A". You ask it to do a paste of that, so of course it will just return itself. Then you do a table, and naturally it tells you that it found "file$A" exactly once. So what you have forgotten to tell us (apart from what your overall goal with this is, which might be helpful in this case) is what output you expected instead.
