[R] adding text to persp

[Mike Lonergan]

A very crude solution is to superimpose two plots.

Though I don't quite understand why:

persp(a)
par(new=T)
persp(a')

puts the plot of a' on top of a (R1.3.1, Windows), while

par(new=T)
persp(a)
persp(a')

doesn't.

Apologies if this is already common knowledge.
If it is unintended, I would prefer nobody fixed it!

Cheers,

Mike.
