Re: [R] sizing and saving graphics in R
Why not plot directly to a bitmapped format, using bmp() or png()? That way you can create a large 'display region' when you open the device. BTW, I guess you are on Windows but you did not say so: bmp() only exists on Windows. On Wed, 30 May 2007, Felicity Jones wrote: Dear R wizards, I am seeking advice on graphics in R.
