I'm using the rtweet package which makes use of the Twitter API which requires a token alluded to by an environment variable.
That environment variable is automatically set up from the Twitter web site and takes the name TWITTER_<username> (where <username> is the name of the user in block letters). That worked fine on my work computer where my username is 'work'. When I copied that working directory to my home computer, the environment variable became TWITTER_HOME but the rtweet package was looking for TWITTER_WORK. There was no error message: just a null result from the search_users() function. I tried editing the ~/.Renviron entry to TWITTER_WORK=/home/home/.rtweet_token.rds That worked for a short time but soon ceased working. Then I noticed a new entry had been automatically added to ~/.Renviron TWITTER_HOME=/home/home/.rtweet_token1.rds So now I had two environment variables which also worked for a short time. No such problem arises if R is run from the bash prompt or Rstudio, but editing functions is so clunky that way. I've used ESS for more than 20 years and find it preferable. R-3.6.3, ESS 17.11 Any ideas what could be causing the token connexion being lost appreciated. -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Average minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
