[R] Current Terminal (console) width

[Bert Gunter]

David et al:

from ?options

"width:
controls the maximum number of columns on a line used in printing
vectors, matrices and arrays, and when filling by cat.

[as Jared said]

...
Some R consoles automatically change the value when they are resized."

So this behavior depends on the unstated by both of you console in
which R is running.


Cheers,
Bert
