[R] Runtime error in R

[Camilo Mora]

Thanks Jeff:

I simplified my code and a single line in which I open a file causes  
this problem. The file opens well in another program and smaller files  
open just fine in R. So it seems the problem is with a default value  
somewhere for how big the files can be. I am suspicious of this as R  
crashes within a millisecond from running the line that tries to open  
the file. Anyway, I wanted to provide this info in case you may know  
what could be causing this Runtime error in r.

Thanks,

Camilo
