conda R (mro) Can't open /etc/ldpaths Error

[Sung Yoon]

After dealing with many frustrated package installation prb. I decided to get rid of R-base in my Lubuntu 14.04 64bit

and did following. But now I have a new prb:

conda install -c mro r

/opt/anaconda/lib/R/library$ R

/opt/anaconda/bin/R: 207: .: Can't open /etc/ldpaths

could b ghost from the past, but when I use 

conda install -c r r

the R version goes back to 3.2.2 rather than 3.2.3-0 (mro), but it works.

[Sung Yoon]

Solved it by copying 3.2.2 R (conda install -c r r) from another machine. It's a script & I do not see a prb with doing it this way, but... 

Anyway done & over with.

echo $R_HOME

:/opt/anaconda/bin$ export R_HOME=/opt/anaconda/lib/R (just put it in /opt/anaconda/lib/R file)

:/opt/anaconda/bin$ ./R_r (This is what I renamed to)

.Rprofile: Setting CRAN to SNU repository

solved the problem, but doc should really reflect this (it almost does but not really)

I also found that cat statement produces problem when compiling a package.

   if (interactive()) { cat(".Rprofile: Setting CRAN to SNU repository\n") }

Seriously, after 20+ years into R/S+ development, user has to search this up?

Anyway, thank u much Ray!

BTW: http://conda.pydata.org/docs/mro.html mentions

export R_HOME=~/Anaconda/envs/my_r_env/lib/R for Linux (which left me bit confused & it was OSX instructions)
