auto.mfrow: Automatically setup par mfrow

In drmjc/mjcgraphics: mjc's graphics library

Description

Determine how many rows and plots to make for a certain number of plots & make the appropriate call to par(mfrow)

Usage

  auto.mfrow(nplots, setup = TRUE)

Arguments

nplots	an integer in [1,49]
setup	if TRUE, then the graphical parameters (par) is set-up if FALSE, and nplots < the number of spaces for plots in the device, then blank plots are added to fill in the unused spaces.

Details

eg 25 plots will cause par(mfrow=c(5,5)) to be called. The function fills in any unsued plotting spots, eg: auto.mfrow(7, TRUE) will set up a device with 3x3 spaces, then when auto.mfrow(7, FALSE) is called after the plots have been made, 2 blank plots will then be 'printed'. NB, you must call auto.mfrow TWICE, once before plotting, and once after plotting, UNLESS you know for sure that the nplots specified will fill all of the spaces.
