Good day, I also see NULL on R start-up. I installed R from source.
$ R-4.1.0/bin/R R version 4.1.0 (2021-05-18) -- "Camp Pontanezen" ... ... Type 'q()' to quit R. NULL > I noticed a couple of error messages at the end of the installation which I thought were harmless. I will reinstall R. The extracted directory and prefix directory were the same, which might be problematic. -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
