Thank you Kit and Nick; now I know that it's just not due my inferior searching of the archive that I have failed to find this. (Why I would want to do this? sometimes I want to repeat a command that is not "byable" by a particular subset , e.g. year, and then use that number for something else. If I forget to populate a matrix in the loop, a table could be an alternative way to get to the data without redoing the loop. My 'algorithmic mind' works this way; it may not be optimal, but at least I understand what I am doing) Thanks again /Barbro On Tue, Nov 22, 2011 at 5:02 PM, Nick Cox <njcoxstata@gmail.com> wrote: > I agree with Kit's emphasis and details. > > In addition, note that -collapse- can be used to produce a small > dataset of means which can be exported elsewhere. > > Nick > > On Tue, Nov 22, 2011 at 3:52 PM, Christopher Baum <kit.baum@bc.edu> wrote: >> <> >> Barbro asks >> >> Is there something similar to tabstatmat or makematrix for the table command? >> >> I would like to use the results from a "table" command as a matrix. >> -- example command >> >> .table var1 var2 , c(mean var3) concise >> >> does a simple solution to this problem exist? >> >> Please help - I do seem to have problems in phrasing the question in a >> way that doesn't produce a huge number of irrelevant results >> >> >> >> No. As you can see from --return list--, the --table-- command does not save anything beyond the sample size. >> Ian Watson's --tabout-- from SSC can be used to do this in a somewhat roundabout manner. >> >> sysuse auto >> tabout mpg rep78 using junk.csv, c(mean price) sum replace f(1) >> insheet using junk.csv,clear >> destring v*, force replace >> >> This will create numeric variables. If you want them as a Stata matrix (why?) you can use mkmat. Note that values not appearing in the two-way table show up as missings, so you might want to mvencode them as zeros (or not). >> > * > * 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/ > * * 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/
