. . help matrix rownames Nick n.j.cox@durham.ac.uk Data Analytics Corp. I used the mat_rapp command this morning - worked perfectly, and saved me time. I have another question, if I may. How do you retrieve the row names and use them in the matrix M=J(n,m,value) command? Any examples of retrieving the names from, say, e(TR)?
