If R crashes, RStudio typically also crashes... so not necessarily news to them. I will say that reproducible examples are nearly always necessary in cases like this to obtain meaningful answers from anyone, and the output of sessionInfo() is also usually needed. On August 8, 2019 8:35:49 AM PD

You may have to contact RStudio about this. RStudio is a separate IDE independent of R -- i.e. developed and maintained by a separate organization from the R project. Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berk

2019-08-08 Thread Luigi Marongiu
Hello, since I am encountering a lot of problems exporting dataframes from julia to R (there is always something wrong with the formatting, probably a missing quote) so I am trying to use Feather to do the job. I have installed Feather in Julia with `pkg.add("Feather")` and imported it with `usin
