Installing ggbiplot from github

Question

I'm trying to install development version of ggbiplotfrom Github. During installation I'm getting the following error message:

library(devtools)
install_github("ggbiplot", "vqv")

In addition: Warning message:

Any idea to figure out this problem. Thanks in advance for your help and time.

Edit

After downloading from Github, also tried

install.packages("vqv-ggbiplot-2623d7c.tar.gz", repos=NULL, type="source")

which produced this error message

It's because your Rlib path has a space in it: C:/Users/Muhammad Yasseen/R/win-library/2.14.

See how in the first error log the warning message was

running command '"C:/PROGRA~1/R/R-214~1.2/bin/i386/R" CMD INSTALL 
C:\Users\MUHAMM~1\AppData\Local\Temp\Rtmpsx4n5u/ggbiplot_0.5.tar.gz
--library=C:/Users/Muhammad Yaseen/R/win-library/2.14' 
had status 1 

In particular, the --library=C:/Users/Muhammad Yaseen/R/win-library/2.14.

This should be --library="C:/Users/Muhammad Yaseen/R/win-library/2.14" to deal with the space.

Using install.packages takes care of the quotes for you - see how your second warning message (when you used install.packages) was

running command 'C:/PROGRA~1/R/R-214~1.2/bin/i386/R CMD INSTALL 
-l "C:/Users/Muhammad Yaseen/R/win-library/2.14"   
"vqv-ggbiplot-2623d7c.tar.gz"' had status 1 

The -l "C:/Users/Muhammad Yasseen/R/win-library/2.14" has quote marks around it, so you don't get the same error.

I had a quick look at the install-github sources, and it constructs the R CMD INSTALL command via:

paste("CMD INSTALL ", built_path, " --library=", .libPaths()[1], sep="")

See how it doesn't surround .libPaths()[1] by double quotes in case of spaces? I'd guess that's your problem.

As to a fix - there seems to be an error using install.packages() on a tar file generated by git (as reported here). So, you can either:

• change your R library location to somewhere without spaces
• unzip the .tar.gz file (I don't know what software does this on Windows) and install from the extracted directories rather than the .tar.gz.
