Dear Anna,
yes I set the path right and this is the answer I get when running Rscript:
Rscript
Usage: /path/to/Rscript [--options] [-e expr [-e expr2 ...] | file] [args]
--options accepted are
--help Print usage and exit
--version Print version and exit
--verbose Print information on progress
--default-packages=list
Where 'list' is a comma-separated set
of package names, or 'NULL'
or options to R, in addition to --no-echo --no-restore, such as
--save Do save workspace at the end of the session
--no-environ Don't read the site and user environment files
--no-site-file Don't read the site-wide Rprofile
--no-init-file Don't read the user R profile
--restore Do restore previously saved objects at startup
--vanilla Combine --no-save, --no-restore, --no-site-file
--no-init-file and --no-environ
'file' may contain spaces but not shell metacharacters
Expressions (one or more '-e <expr>') may be used *instead* of 'file'
See also ?Rscript from within R
So I guess it is working properly?
