I assume that prim, etc. are columns of your data frame, mydata. Ergo, the
error message "prim not found" as 'prim' etc. does not exist in the Global
environment.
exclude <- with(mydata, prim == -9, etc. ) should get what you want to
evaluate your second subset statement if I have understood corre
Thanks. YES the second call to subset is there, trying to use my failed
definition of "exclude". Read on..

My definition of exclude is rejected.
Help please? Thanks.

What you are probably looking for is the %in% operator:
with(mydata, sum(table(X1[X2 %in% 5:8])))

recycled if not long enough

Hello-
I have some code that looks like this:
with(mydatalocal, sum(table(Service[Time==5:8])))
This is designed to add up the numbers of responses between the Time
codes 5 to 8 (which are integers and refer to quarters). Service is
just one of the variables, I'm just trying to count the number
6 matches
