Jens,

Im not exactly sure what you meant by "principles of calling batch
procedures from other software into R" !?!

Would you like to know how R import data from ohter software formats? How
other sotwares export into R format? Access these codes? Is that it?

R has a lot of different functions to import data from different formats,
including, Stata, SAS, SPSS, SQL, MySQL, xls, xlsx, ols (this last a think
is available only for UNIX), csv, dbf, revman, and others! I never heard
that other software could export to R workspace! However, I have a
Stat/Transfer (2007) that has an option to export to R workspace format! Im
not sure it work properly though!

Abraço forte e que a força esteja com você,
