Ok friends, I tried but I not know! I'm a Linux SysAdmin and
Stadistical and
i working to migrate all the software in my workplace to free or open

know, everything was relatively easy. But i work with SPSS and I
produce
tables from polls with CTABLES and FRECUENCIES tables. In my
migration party
I think R is the best option but need replace SPSS functions and
procedures.
I know that sucks but it's.
In the attach you will see an example with a short output like I
need,
please I'm starting with R and i 'm study but i need to find
something to
replace this frecuently output while grows my experience in R.
This is the syntaxis used:
FREQUENCIES
VARIABLES= REGION
/ORDER= ANALYSIS .
CTABLES
/VLABELS VARIABLES=zona V1 V3 V4 V5 V6 V7 V8 v51
DISPLAY=DEFAULT
/TABLE ZONA [C] +V1 [C] +V3 [C] +V4 [C] +V5 [C] +V6 [C] +V7 [C]
+V8 [C]
BY v51
[C][ROWPCT.COUNT COMMA40.1, TOTALS[COLPCT.COUNT COMMA40.1]]
/SLABELS VISIBLE=NO
/CATEGORIES VARIABLES=ZONA ORDER=A KEY=VALUE EMPTY=INCLUDE
TOTAL=YES
LABEL='Total'

R is grand, great and biggest.
Thanks for all.
I would recommend getting a copy of Bob Muenchen's book:
R for SAS and SPSS Users
http://sites.google.com/site/r4statistics/the-books/r4sas-spss
There is a free smaller version here:
http://sites.google.com/site/r4statistics/free-version
and you can get a full copy from Amazon.com:
http://www.amazon.com/SAS-SPSS-Users-Statistics-Computing/dp/0387094172
That would be the best place to start, relative to moving from SPSS
to R.
Part of the challenge is not just replicating SPSS code and output
in R, but understanding the conceptual differences between the two,
so that you can take advantage of R's approach/philosophy in
conducting data analysis.
Another place to get useful code is the UCLA Statistical Computing
website. At one time that group was very negative about using R, but I
think the feedback or demand has reversed that attitude and there are
now quite a few worked examples of common task in which SAS, SPSS,
Stata and R are applied using the same data.
