Hi everybody, on ?plotmath it can be seen that mathematical expressions like a greek letter could not be used for x- and y-axis labels in 'persp' plots. Unfortunately, this is exactly what I want to do: I need an expression(rho) to label the y-axes. Does anybody know a way to solve the problem. Further, Latex works very well by using the command tilde{y}^{[dip]} but I have some troubles in R (for instance, as a 'main' argument in a simple plot), probably due to the square brackets. The command expression(tilde(y)^(dip)) works, but what I want to get are indeed the square brackets.
Thanks in advance.
