What is the correct format for the shebang line and what options are allowed or necessary along with this?
I find plenty of blogs and opinions, but few authoritative answers. I want an R script to run and update packages periodically, with a cron job that launches it. What is necessary to put in line one of the R program. Aside from the basic part #!/usr/bin/Rscript what else can there be, or should there be? Various people suggest adding things like "--vanilla" but those seem not to be accepted, at least on RedHat EL 6 with R-2.15.1. I'd like to run this with a command line like: $ R-labSelectInstall-02.R > /tmp/Rupdate.txt 2>&1 so that all the standard output and err goes to a text file, but I've not found a way to make it work comparably to the R command line option --vanilla or such. # ./R-labSelectInstall-02.R --vanilla 'ARNING: unknown option '--vanilla See what I mean? -- Paul E.
