[R] R hangs on startup

[Vineet Gupta]

Hi,

Thanks to all of your answers. I have found that when I open a code file
with RStudio, it opens correctly, and the R session appears to work ok.

However, when I startup and R session or an RStudio session, then the R
session hangs.

I will try the other suggestions below to see if I can solve the problem.

It's not obvious that your problem is OS-specific, nor is it necessarily the
case that your problem is a bad .RData or .Rhistory file, though it's worth
trying to delete them.

BTW, does R work properly outside of RStudio?

Generally R will save the workspace on exit (if you ask it to) in the
working directory. Under RStudio this would normally be the directory of
your current project, or, if you're not using a project and haven't changed
your working directory, in your Documents folder.

You're looking for files named .RData (the workspace) and .Rhistory. The
former may be hidden in Windows Explorer  if you don't display
known-to-Windows file extensions, but you'll still see the R icon. .Rhistory
isn't a registered extension and should appear in any event. Right click on
these files and delete them.

It's generally a good idea *not* to hide file extensions. In the Windows
Explorer "View" tab, check "File name extensions."

I hope this helps,
 John
