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.
