"package ‘mgcv’ could not be loaded" only in RStudio

Question

I'm getting this error when trying to load the package "TSA" in RStudio:

Loading required package: leaps
Loading required package: locfit
locfit 1.5-9.1   2013-03-22
Loading required package: mgcv
Loading required package: nlme
Error : .onAttach failed in attachNamespace() for 'mgcv', details:
  call: formatDL(nm, txt, indent = max(nchar(nm, "w")) + 3)
  error: incorrect values of 'indent' and 'width'
Error: package ‘mgcv’ could not be loaded

I tried reinstalling mgcv and TSA, but it didn't help. However, when I load TSA from the R command line, it works without problem.

How can I fix this issue?

R version 3.0.2 (2013-09-25)

RStudio 0.97.551, 64 bits.

UPDATE:

I tested this issue in a 32 bit installation of RStudio and it worked flawlessly. I'm not sure what is the real culprit here.

Answer 1

In RStudio, just resize the right side to increase the width of the windows. Now try library(mgcv) again, and it works!

Answer 2

For the reference of anyone encountering a similar problem under Windows 7, I had the same problem with the forecast package - one day, it just wouldn't load in RStudio (worked fine in R). Had to completely uninstall both R and RStudio, making sure to delete C:\Program Files\R and C:\Users\[username]\AppData\Local\RStudio-Desktop and reinstall before it would work again. Wouldn't work if I just deleted the RStudio stuff and tried to keep the R files.
