[R] complex expression with plotmath

Hello everyone,

I want to define a function that receives the name of two variables (may include Greek letters and subscripts) and uses them into the title of a plot.

My best attempt is the following:
myplot <- function(var1, var2) {

    v=paste(var1,"==1 & ",var2,"==2");
    plot(1:10, main=parse(,,v))
}

But when I call it with something like myplot("Q[i]", "Delta[j]") I get "&(Q_i=1,Delta_j=2)" as title when I want to get "Q_i=1 & Delta_j=2".

Is there any solution within R? (I don't want to use psfrag and Latex to post-process the plot)

Why R does not have support for full Latex expressions? (as Matlab f.ex.). IMHO plotmath is not good enough.

Thank you all.

Felipe
