This case is related to TIBCO support case #01791114 which is submitted internally in TIBCO feature requirements database.
Whilst applying best practices is obviously something that should be done: It appears that the profiler in R-Studio is broken with TERR (using TERR 5.0.0 on my laptop … - so, yes, one version higher than when running “production” in pdf’s Exensio -Spotfire- TERR client, which is 4.4.x): It tells me when invoking (and stopping) profiler: Warning in Rprof : this function not yet implemented This makes performance optimization a very difficult game! What to do?
