Ah, interesting.

gen x = Xy[_n,1] in 1/16

Check out the undocumented command -_matplot-.Nickn.j.cox@durham.ac.ukNick Winter I'm wondering if there is a way to convert the values held into a matrixinto a graph (ie, into a serset that serves as the basis for a graph)directly, without first making the matrix into variables?Why I'm curious:I'm thinking about revising my -oprobpr- command, which plots predictedprobabilities after order l/probit models. The new -margins- commandcan fairly easily calculate what's required for the plotting, and thoseresults can be saved as a matrix, using -margins-'s -post- option.So I'd like to plot the estimates returned in e(b) against values in e(at). I can put this stuff all together in one matrix, eg: sysuse auto probit foreign mpg price weight margins, atmeans at(mpg=(12(2.9)41)) post mat b = e(b) mat X = e(at) mat Xy = X , b'Then I'd like to create, eg, a line plot of the final column (named y1)against the first column (mpg).I can, of course, use -svmat-, graph the relevant variables, and dropthe variables.But I'd love a more elegant solution. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
