问题
For some packages like doMC & doSMP, i get the warning & inability to library(doMC). As shown below, i have no problem with subselect thus no file/directory permission issue. Also tried repo=http://cran.us.r-project.org & others, no luck. please advise.
ps: for the unexpected Japanese characters, i have no clue; i assume that is a separable issue; no response yet from support.rstudio.org/help/discussions/problems/6009-japanese-characters-show-unexpectedly

I assume it's not available to you because you're using Windows. The doMC package has never been available on Windows because it depends on the mclapply function, before in the multicore package and now in parallel. I haven't heard of any issues with doMC in R 3.0.0.
The doSMP package was intended to be the Windows alternative to doMC. I believe it was eventually taken off CRAN because of problems building it on newer versions of GCC.
The doParallel and doSNOW packages are probably the most popular foreach backends available for Windows.

If you want to install it for windows, here it how you can:
install.packages("doMC", repos="http://R-Forge.R-project.org")
I did it for R 3.2.3 version and it works well.

I was facing the same issue with RTextTools, as RTextTools is now not available on CRAN. I have Download RTextTools From Given Link
https://cran.r-project.org/src/contrib/Archive/RTextTools/
and copy RTextTools_1.4.2.tar.gz file in project root folder then run this command in project folder in terminal
"R CMD INSTALL RTextTools_1.4.2.tar.gz" After running this command I receive below error "ERROR: dependencies ‘SparseM’, ‘randomForest’, ‘tree’, ‘e1071’, ‘ipred’, ‘caTools’, ‘maxent’, ‘glmnet’, ‘tau’ are not available for package ‘RTextTools’" Now install each dependencies from RStudio or RConsole (Any Editor used by you) by simply running this code
install.packages("caTools")
Install all 9 required packages One By One (In My Case it was 9 Packages Dependencies required by RTextTools) all packages will be installed except 'maxent'
Now download maxent from the given link
https://cran.r-project.org/src/contrib/Archive/maxent/
and copy maxent_1.3.3.1.tar file in project folder then run this command in project folder in terminal
"R CMD INSTALL maxent_1.3.3.1.tar"
Now For RTextTools Run this command again in Terminal
"R CMD INSTALL RTextTools_1.4.2.tar.gz"
All is done Now.. But the Last Step is Load the RTextTools using
library(RTextTools)
You will see one more Error: Load SparseM Now Loading SparseM use code below library(SparseM) and in the last Load RTextTools library(RTextTools)
