How to increase the number of columns using R in Linux

Question

This may seem menial, but it affects my productivity. I am using R in terminal mode on Linux. Unlike the Windows IDE, Linux limits the number of columns to 80, thus making harder the inspection of data sets. Is there a way to set the max number of columns?

Answer 1

Here is a function I have in my ~/.Rprofile file:

wideScreen <- function(howWide=Sys.getenv("COLUMNS")) {
  options(width=as.integer(howWide))
}

Calling the function without the howWide argument sets the column to be the width of your terminal. You can optionally pass in the argument to set the width to an arbitrary number of your choosing.

Almost like Josh's suggestion, but less magic :-)
