[R] limit digits in text()?

[Bill Simpson]

I am labelling the axes of a persp() plot manually using text(). For
one spot in the plot I use:
text(-.62,.37,max(dprime))
The problem is that the label is printed as 1.6456330961.
I would like 1.6.

I tried options(digits=2) and str(digits.d=2)--no effect. (I don't like
these methods anyway since I just want to modify how the label in the plot
is printed; I want to print all the digits otherwise.)

How should I do it?  Is the only way to first set options(digits=2), then
compute dprime, then do text(), then when done reset options(digits=10)?

Thanks very much for any help.
