Current Terminal (console) width
The answer is UI-specific.
In the supplied-by-R-core Windows GUI for R, options("width") is the
current width of the command window. If you run R in a cmd.exe window
instead of the GUI you can get the width of the cmd window by doing
some string manipulations on the output of shell("mode con",
intern=TRUE). E.g.,
as.integer(sub("^.* ", "", grep(value=TRUE, "Columns:", shell("mode
con", intern=TRUE))))
(Setting options(width=120) when using the cmd window does not seem to
affect the input echoing - it seems to always be 80 characters.)

Ben,
That options control is about the size of what is printed. I'm looking for
the actual size of the window in real time.
options('width') ## returns 80
resize the terminal window
options('width') ## returns 80
Sys.getenv('COLUMNS') ## returns current window width
resize the terminal window
Sys.getenv('COLUMNS') ## returns a different value
This however does not work on a Windows OS.

Hi, Have you looked at
options("width")
$width [1] 80
and does that get at what you need? Ben

Will return the current width of the R terminal (console) but this does
