Thanks! but ...
While that works great on _my_ linux boxes (on which I installed R),
on the cluster where I need to run this (where I do *not* have root)
me@foo:~ $ which Rscript
> /usr/bin/which: no Rscript in
> (/home/me/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin)
me@foo:~ $ find /share -name 'Rscript' | wc -l
> 0
me@foo:~ $ which R
> alias R='/share/linux86_64/bin/R'
> /share/linux86_64/bin/R
So I'm wondering:
1 Is there a way to do `Rscript -e` with plain, commandline R?
2 What should my admin have done to install both Rscript and R?
(Alternatively, what should I tell my admin to do in order to make
both Rscript and R available?)
3 Is there any reason to install R without Rscript? (Alternatively,
when I ask my admin to install Rscript, is there any objection
I should anticipate?)
thanks again, Tom Roche <[email protected]>
