Sorry folks but again I have failed in my understanding of how to do a very
simple thing. I've read the various texts and searched the help archives
but no positive result so far.
I want to remove all the rows in a data frame where one of the variables has
negative values. In approx Stata pseudocode:
drop _all, if( x < 0 )
Please either point me to relevant sections of the docs or supply me with
solution - I'm sure it's very simple.
