Cheers Paul.
Its a very good point. Although i am curious how badly i can damage my R
install by running as root. I always ran R in windows with admin.
privileges without problems (touch wood). Probably best to never find
out by sticking with user privileges.
However, even for taking care of R install/maint. i'd prefer to do this
interactively within Emacs rather than the terminal. Motivated by this,
i'd still like to find out how to invoke R with root privileges.
I've also reposted the original email on perhaps a more appropriate
forum at: ess-h...@stat.math.ethz.ch

Esteemed UseRs and DevelopeRs,
Apologies if this question belongs else where, but it does concern R's
package installation/maintenance.
How does one start R within Emacs/ESS with root privileges?
I tried without success:
M-x sudo R
Why i'm motivated to do so:
It seems logical to me, as the only user of the PC, to keep my R
library consolidated in the universal library rather than splitting
into universal and user libraries. Hence the desire to run R as root.
Hi Karl,
Why the need to install packages in root? As you are the only user there
is not reason to install them system wide (to make them available to all
users, which is just you). Installing the packages in your homedir
solves your problem much easier, without the need to run R as root
continuously. I think you should not run anything as root if it is not
absolutely needed, which could potentially damage your system
(accidentally overwriting something).
hope this helps,
Paul
In addition, it's nice to be able to install packages 'on the fly'
when and as needed and not need to launch a separate R session (as
root) in the terminal just to install a package.
Migrating from windows, i'm completey new to linux (ubuntu) and am
seeing for myself if Emacs/ESS is as good as its purported to be. So
maybe my motivation is nonsensical to expereinced ESS/R users. If so
i'd really appreciate tips on efficient package
installation/maintenance using Emacs/ESS.
TIA,
karl
