Subject | st: Subsetting a -return- matrix in a single step |
Date | Fri, 10 Sep 2010 17:50:37 -0400 |
Dear Statalisters, I would like to subset a -return- matrix. In the past I used two steps but now hope to upgrade to the 1-step solution, if it exists? Thanks, Bert *** Example: using tabstat just to produce some r(matrix) to play with tabstat foreign turn weight length headroom, stat(mean sd q) save return list mat list r(StatTotal) *** Say I want the first 3 rows and 2 columns of this matrix. Can the following be done in a single step? mat A = r(StatTotal) mat A = A[1..3,1..2] mat list A *** Obviously this generates a syntax error mat B = r(StatTotal)[1..3,1..2] * * 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/
