Dear R-users,
I am looking for a R function that would be the equivalent of the
SAS proc
freq (

documentation/cdl/en/procstat/63104/HTML/default/
procstat_freq_sect006.htm).
The table, ftable, xtabs functions are close but do not quite offer
the same
capabilities (e.g. they just return counts and no %ages as far as I
could
tell).
I wanted to check with the group if there would already be such a
function
in base or in a contribution package, before I start coding my own
function.
There are a couple of efforts to imitate the Proc FREQ output in the
archives. If you use one of the several search facilities (e.g. RSeek,
the RSiteSearch function or the ??? function in the sos library) you
will get links to those:
(A test of this theory with RSeek pointed to the CrossTable function
in gmodels.)
Try also with...
?RsiteSearch
RSiteSearch()
Or with ...
require(sos)
???"proc freq sas"
