Try
options( "width" )
source( "your-script.R" )
options( "width" )
I would guess that your script is changing options("width") and that
resizing silently changes it to a suitable value.
If so you can do this
old.options <- options( "width" )
source( "your-script.R" )
options( width = old.options$width )
