What is the function set()? Is that a typo? When I type ?set I get
nothing, and when I try to evaluate that code R tells me it can't find the
function.

Yeah, it's a typo. (S)he meant ``subset''.

The message tells you everything - there is no function 'set' in the
workspace you are using. Did you forget to load a library? What is the
context in which you are trying to use it?

Dear R-help members,
Apologies for the trouble.
I have a question :
Essentially, I have a dataset which stores genetic variations for individual
patients. Each individual patient can have more than one variation, and each
new record corresponds to a new variation (thus, both individual patients
Hi,
I figured a workaround to my problem, but if anyone has any advice on how to
express a function in tapply to achieve the same outcome, that would be
awesome and I'd learn something about functions!
The workaround was
tapply ((data$Variation.Type %in% c(2,3)), data$Patient, sum)
Thanks.
how about:
d1=data.frame(pat=c(rep('a',3),'b','c',rep('d',2),rep('e',2),'f'),var=c(1,2,3,1,2,2,3,2,4,4))
ds=set(d1,var %in% c(2,3))
with(ds,tapply(var,pat,FUN=length))
hth,
