[R] margin text mtext

[Christian Hoffmann]

Hi all,

Fiddling around with "mar" and "mtext" I got stuck:

plot.pcaX <- function(tit,lab) {
  on.exit(par(oldpar <- par(oma=c(4, 2, 4, 2), mar = c(4, 4, 2, 1)))) # ??
  split.screen(figs=c(3,3))
  for (i in 1:9) {screen(i);  plot(rnorm(100),rnorm(100)) }
  mtext(tit, side = 3, line = 1, outer = TRUE, cex = 1.5, adj = 0.5)
  mtext(paste(lab,", ", date()),side = 1,line=0,outer=TRUE,cex=0.5,adj=1)
  close.screen(all=T)
}

plot.pcaX("test","test.ps")

The plots are arranged without any margins, and "test" and "test.ps" will
not be printed on the plot.
