AFAICR you supposed to deal with this via $PATH and just pick one:
Ie with
edd@max:~$ grep ^R_HOME_DIR /usr/lib/R/bin/R /usr/local/lib/R-devel/bin/R
/usr/lib/R/bin/R:R_HOME_DIR=/usr/lib/R
/usr/local/lib/R-devel/bin/R:R_HOME_DIR=/usr/local/lib/R-devel/lib/R
edd@max:~$
I get, respectively,
edd@max:~$ R --version | head -1
R version 3.1.2 (2014-10-31) -- "Pumpkin Helmet"
edd@max:~$ PATH="/usr/local/lib/R-devel/bin/:$PATH" R --version | head -1
R Under development (unstable) (2015-02-22 r67876) -- "Unsuffered
Consequences"
edd@max:~$
and I have R-devel aliased to RD and R-devel in /usr/local/bin.
