Thanks, Patrick. Printing wide is sometimes needed. options(width=120)
just works, but I need to changed it back to 80 every time for normal
printing. Sort of tedious.
I'm just curious why print.data.frame does not take an argument of
width=120, just like in print.factor.
## S3 method for class 'factor':
print(x, quote = FALSE, max.levels = NULL,
width = getOption("width"), ...)
