[R] Plotmath integral gets horrible with URWPalladio

[Paul Smith]

Dear All,

With the following code:

pdf(file="figure.pdf",family="URWPalladio")
plot(0,0,type="n")
text(0,0,expression(integral(f(x)*dx, a, b)))
dev.off()

the integral symbol gets horrible. With other fonts, the same does not
occur. Is there some way of using Palatino-like fonts with a nice
integral symbol? I am using R 2.5.1 on F7 (Linux).

Thanks in advance,

Paul
