The defaults for postscript()
paper = "default"
onefile = TRUE
horizontal = TRUE
(it seems) date from the days when people used to used this to send plots
directly to a postscript printer via print.it=TRUE. I haven't done that
for years, and it seems that our current generation of students don't even
know the concept. It seems 'horizontal = TRUE' is particularly difficult
Given that I suspect almost all uses of postscript() are to produce plots
to be viewed on-screen or incorporated into another document, a more
appropriate set of defaults would be
width = 7, height = 7
paper = "special"
onefile = FALSE
horizontal = FALSE
which would have the advantage of using the same default aspect ratio for
plots as all (?) other R graphics devices.
Does anyone see a reason not to change the defaults?
