I don't see a "second one". Looks like you forgot the subset function call? On October 15, 2021 6:23:56 PM PDT, Steven Yen <styen at ntu.edu.tw> wrote:>The following "subset command works.

Please excuse my brevity.
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

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 correctly, as it will look for those names within mydata.
