this is a feature request or alternatively a request for help finding another solution... When doing "foreign language=xxx --send-data" I would like to specify a list of series that is being sent, instead of the whole dataset, e.g. like this: "foreign language=xxx --send-data=mylist" where of course 'mylist' must exist. This way I could (trivial example ahead) run a regression in R while controlling from the gretl side the exact variables that I want to use in there, and _without_ having to know their names within R. Inside R I would just use the generic 'gretldata' name for all the data that is passed. The ordering of series/variables inside the list would be important, however. Or can this be achieved already somehow?

That would not be difficult. It's now in CVS; snapshots will follow.

Well the gretl standard so far (for gmm, mle and so forth) has been to append options at the very end, so why not here, too? Or perhaps one could use the 'setopt' command which Jack explained to me the other day: <hansl> list tobepassed = EMP WAGE setopt foreign --send-data=tobepassed foreign language=R print(gretldata) end foreign </hansl> This would be nice I think.

Yes, that will work. But I've just committed a change to CVS such that your original formulation will work too (i.e. giving the --send-data option on the first line of the "foreign" block).
