getting the by() function to work properly
...t might be the issue. Essentially I have compiled a large list of data coming from about 30 subjects with 88 trials each and I am trying to get that function to apply to each subject without having to manually attach each subject's data. The entire filename is 'ss2' so when i run
>ss2f3=f3(ss2)
>ss2f3
everything is fine. However when I try to use the by() function:
>by(ss3, sub, f3)
#sub=subject header in the data
I get the error message: " Error in var(x, na.rm = na.rm) : missing observations in cov/cor "
There are no missing observations anywhere in the data so...
