There are many ways of doing what you want, which one is best for you
depends on what you want to do with them.

The proportions aren't saved, but the counts are. The easiest way is to
use the -proportion- command.
*-------- begin example ---------------
sysuse auto, clear
recode rep78 1/2=3
tab rep78 foreign, row nofreq
proportion rep78 if foreign == 1
di [rep78]_b[3]
*--------------- end example -------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )
> (b) Now, is there a way to save the whole table above to a matrix?
> Hopefully, without having to do (a) repeatedly many times?
*------------- begin example ----------
sysuse auto, clear
proportion rep78, over(foreign)
matrix list e(b)
*-------------- end example -----------
> And one more question: if I do something like

see -help ereturn-
*----------- begin example -----------
sysuse auto, clear
reg mpg trunk length
erturn list
matrix list e(b)
di _se[trunk]
di _b[trunk]
*------------ end example -------------
Hope this helps,
