[ESS] bug in ess-remote?

Why is ESSR.rda fails to download? Sending files to remote shell is very
unreliable, and, quite frankly, I don't know the reason for that and
have no clue how to solve it. So placing ESSR.rda on the web was an easy
solution. You need to instrument ess--R-load-ESSR and see why ESSR.rda

Tramp is stuck because of an error on process loading. C-g and then go
to the *R* buffer and see what is going wrong. Most likely R has not
been found.

Thanks for the reports,
