the second command doesn't tell R that the variables are in the data.frame
mydata.
you will need
exclude <- with(mydata,
prim==-9 | etc)
also you will need logical negation !
not arithmetic negation -
-c(TRUE,FALSE)
[1] -1 0
as.logical(-c(TRUE,FALSE))
[1] TRUE FALSE
!c(TRUE,FALSE)
[1] FALSE TRUE

The following "subset command works. I was hoping the second would as well but
it does not.
My definition of exclude is rejected.
Help please? Thanks.
