I guess you need to specify the lib directory

"lib character vector giving the library directories where to install the packages. Recycled as needed. If missing, defaults to the first element of .libPaths()"


Check sys.glob!


Try Sys.getenv ().

Hope this helps.

Dear Sir/Madam,

This is Chiao and I am writing to know how to solve some problems I met regarding the impossibility to install packages including igraph, devtools, and Matrix.

According to my lecturer, one way to solve the problem is to change  the security setting of my R folder and also Specify a folder for installation of the libraries (for each package). 

However, my mac laptop still can not work. The console showed that 
> install.packages("igraph") 
trying URL 'https://cran.rstudio.com/bin/macosx/mavericks/contrib/3.3/igraph_1.0.1.tgz'
Content type 'application/x-gzip' length 6598610 bytes (6.3 MB)
downloaded 6.3 MB

tar: Failed to set default locale

The downloaded binary packages are in
[please refer to the attached screen shot 'Failed to..']

For the package 'devtools', 'Matrix', they both had the same warning.

After searching on website, I followed the instruction that put a code sentence at the final line like

system("defaults write org.R-project.R force.LANG en_US.UTF-8") 
[as the attached screen shot 'system..' ] 

I have no idea what to do next. Please help me to solve the problem.
I am looking forward to your reply.

Kind regards,
