Re: st: Matrix help

["Data Analytics Corp." <dataanalytics@earthlink.net>]

Good morning,

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)?

Thanks,

Walt
