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

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
Installing package(s) into ‘C:/Users/Muhammad Yaseen/R/win-library/2.14’
(as ‘lib’ is unspecified)

Answer 1

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.

Answer 2

You can't unzip the .tar.gz because it cleans up that file quicker than you can grab it (I've watched it appear and get deleted again). Correct me if I'm wrong, but I also can't get devtools from github for teh same reason :S
