Arrange plots within a window

If you want to get a number of plots in the same window or figure, the arrangePlots function can help you find the adequate number of rows and columns in which to arrange them. This can be especially useful inside a function that can generate plots whose number you don’t initially know — it is used e.g. in the optiThresh function. Both these functions are included in the modEvA package (Barbosa et al. 2014).

arrangePlots  <- function(n.plots, landscape = FALSE) {
  # version 1.0 (16 Sep 2013)
  root <- sqrt(n.plots)
  large <- ceiling(root)
  small <- round(root)
  if (landscape) plots.rc <- c(small, large)
  else plots.rc <- c(large, small)
  return(plots.rc)
}  # end arrangePlots function

Usage examples (e.g. for 6 plots):

par(mfrow = arrangePlots(6))

for(i in 1:6) plot(i)

par(mfrow = arrangePlots(6, landscape = TRUE))

for(i in 1:6) plot(i)
