I checked the environment variables in Emacs and also in R (using =
Sys.getenv). all environment variables are set correctly (I am now also =
using =93exec-path-from-shell=94 to make sure that Emacs is reading =
system environment variables).
It is absolutely strange. I only get the error when I export the org =
file, but not if I execute R code chunk by code chunk sequentially.

best, jo
