Expert R users, what's in your .Rprofile? [closed]

Answer 1

I've got this, more dynamic trick to use full terminal width, which tries to read from the COLUMNS environment variable (on Linux):

tryCatch(
  {options(
      width = as.integer(Sys.getenv("COLUMNS")))},
  error = function(err) {
    write("Can't get your terminal width. Put ``export COLUMNS'' in your \
           .bashrc. Or something. Setting width to 120 chars",
           stderr());
    options(width=120)}
)

This way R will use the full width even as you resize your terminal window.
