Hi,
I stumbled again over the situation that gretl offers import support for
quite many third-party formats, but not explicitly for .Rdata files. I
have rechecked the mailing lists and AFAIU this was due to lack of
low-level standardization or unstable format specifications.
In practice I have been given a Rdata file which gretl apparently tries
to treat as a csv variant but cannot open. (I know I can go via native R
and that's what I will do, but that's not the point.)
So I was wondering if in the meantime things have stabilized enough;
perhaps this Library-of-Congress page is helpful? :
