[R] short plots: lwd, margin and postscript behavior

[Cézar Freitas]

Hi all.
I'm working with a short plot (3x3 inches), but the
results (via postscript command) are not nice. The lwd
command don't affect the lines (that are very large)
and the margins don't change using oma, mai, mar, ...
Below I put an example. Moreover, save the graphics
via postscript command isn't working well (see the
attached ps).
Thanks by the help,

Cezar Freitas.

#Example:
#data
  scores<-c(2.0, 0.0, 5.0, 5.0, 5.0, 2.0, 0.0, 5.0,
2.5, 4.0, 5.0, 0.0, 5.0, 0.0, 2.0, 5.0, 5.0, 2.0, 3.0,
3.0)
  q<-summary(scores)
  gra<-hist(scores, breaks=((0:11)/2-.2), plot=FALSE)
  yy<-ceiling(max(gra$counts)/10)*10
  yz<-yy/12

#plot via postscript
  postscript("test.ps", width=3, height=3,
horizontal=FALSE, family="Times", paper="special")

  hist(scores, breaks=((0:11)/2-.2), xlim=c(-1,6),
ylim=c(-yz,yy), main="scores", ylab="Freq",
xlab="math", cex.axis=.3, cex.main=.3, cex.sub=.3,
cex.lab=.3, mgp=c(1.5,.5,0))
  boxplot(scores, horizontal=1, add=1, at=-2*yz/3,
boxwex=1.5*yz, bty="n", axes=FALSE)
  points(q[4], -2*yz/3, col=1, pch="+", cex=.5)

  dev.off()
