‘width’: controls the maximum number of columns on a line used in
printing vectors, matrices and arrays, and when filling by
‘cat’.
Columns are normally the same as characters except in East
Asian languages.
You may want to change this if you re-size the window that R
is running in. Valid values are 10...10000 with default
normally 80. (The limits on valid values are in file
‘Print.h’ and can be changed by re-compiling R.) Some R
consoles automatically change the value when they are
resized.
