org 8.2.3 ?? The last 8.2.3 release I see on git is 2013-11-15 05:58:32 (GMT) The ess 14 patch showed up on 2014-09-18 01:10:40 (GMT). > Archlinux, but only if I don't start the R session first. If I do 'M-x > R' to manually start an R process it works fine, but if there is no R > process already running I get 'Error: could not find function > ".ess.eval"' Yes. (R) starts the session asynchronously, so in programmatic use subsequent commands can jump the queue and confuse the process. This did not seem to matter before ess 14. The 2014-09-18 01:10:40 (GMT) patch forces a wait for (R) to finish before anymore commands are sent to the session. So either update org-mode or downdate ess or replace org-babel-R-initiate-session with the current version and recompile. HTH, Chuck
