ggplot2 loading failure

[Seongjin Choi]

There has been no problem with RStudio and ggplot2 so far.

ggplot2 won't load with the following error message.

sh: otool: command not found

Error : .onLoad failed in loadNamespace() for 'tcltk', details:

  call: system2("otool", c("-L", shQuote(DLL)), stdout = TRUE)

  error: error in running command

Error: package or namespace load failed for ‘ggplot2’

I am not familiar with this error message. 

Please leave any advice to resolve this issue ASAP.

Best,

Seongjin

Hii,
Even after uninstalling and reinstalling a couple of times and even then I am getting the error in ggplot2 package.

Error: package or namespace load failed for ‘ggplot2’

Please help me out

Did you try to reinstall plyr?

Do you see a "plyr" folder under: 'C:/Users/XXXXX/Documents/R/win-library/3.1/?
