Dear Listers,
I'm running the following code:
twoway scatter ratio month, by(status) c(l) xlabel(1(1)12)
twoway scatter ratio1 ratio2 ratio3 ratio4 month, by (status)
connect(l l l l) xlabel(1(1)12)
where status is a dummy. Stata returns an r(198) error, and it
happened when I added the by-option. I would also like to use
by(status, total) later on. Any suggestions? Thanks in advance.
