Hi Gabor,
I see often this posting cited, whenever the question about using X12 from
within R arises, and every time I go to sourceforge to read if there is
something new. But what I find is:

1)  One can run R from within Gretl because:"*gretl* is designed as a very
user-friendly econometrics package. While it is also reasonably
sophisticated, it lacks some of the specialized statistical methods that a
working econometrician might desire..... From gretl, you can save the
current data set in a format suitable for analysis using R ...".

2) There is X12 support in Gretl in the sense that  X12 is __distributed__
with Gretl. Further, one can select a variable from his Gretl data set and
run X12 on it.The results will be saved into the current Gretl data set.

I see the link as follows:

                     R <---| Gretl |---> X12

and what is asked for is R ---> X12, i.e. something like

       data(mydata)
       library(X12)
       X12:::doSomething(mydata)

I would very much appreciate if somebody can explain me how can I perform
X12 analysis on my R data set? Has somebody considered 'packaging' X12 in R?

Best regards,
Valentin
