One of the R pluses *is* in the graphics, IMO.
1) It allows Mathematical Text !!!
Unfortunately, this is still mostly undocumented.
However, Paul Murrell & Ross Ihaka have a paper submitted which
A bit (:-) exaggerated,
`Basically, R has TeX inside' [this is me, not the above authors..].
2) It allows you to specify line types `very detailed'
=> ?par has
lty: The line type. Line types can either be specified
as an integer (1=solid, 2=dashed, 3=dotted 4=dot-
dashed) or as one of the character strings
`"solid"', `"dashed"', `"dotted"' or `"dot-
dashed"'. Alternatively, a string of up to 8
characters may be given, giving the length (in
points) of line segments which are alternatively
drawn and skipped. For example, `"44"' is dashed
and `"13"' is dotted.
3) You can more easily specify colors and color palettes.
plot(x,y, col = "purple")
par(ask = T)
4) You have more par()'s to specify the color and other things of
main,sub, [xy]lab, .., separately.
5) There's gamma correction for color.
6) You can set or fix the aspect ratio of plots quite generally
`` par(asp = ..) ''.
This makes V&R "eqscplot" unnecessary and allows much more;
further, it allows manual rescaling of the plot and keeps the aspect
