in applied work with a 'foreign' block where data is sent to R, I had

the gretl side the series to another one, which then --as described in
the guide-- only contains numbers.

Give an example script, please.

Here's an example (where the data itself is based on the example in chapter 16):

<hansl>

open data4-10
markers --to-array=S
series state = S
# print state --byobs

foreign language=R --send-data=state
    print(gretldata)
    print(as.matrix(gretldata))

end foreign

</hansl>

I'm not saying it's wrong that the strings are transferred, the question right now is if it's intended. But then I was also a bit surprised that in this example as.matrix still seems to keep the strings.

thanks
