[R] Hmisc curve label size & cex

[Brian O'Connor]

R-Masters,

I need to produce high resolution line plots and place labels on the 
curves. It seems that cex must be high relative to the other cex 
values in order to produce sufficiently large & legible tick labels 
at high resolutions. But high cex values cause the curve labels to 
become gigantic when using Hmisc. I've struggled and searched the 
archives, but cannot find a way of controlling the sizes of the curve 
labels in this situation.

These commands produce the problem on my PC using XP:


png("trial.png", width=3000, height=2400, res = 600, pointsize=12 )
par(ann=F, font.main=1, font.lab=1, font.axis=1, cex=5, cex.main=1, 
cex.lab=1, cex.axis=1,
    lwd=12, las=1, mar=c(4, 4, 2, 2)   )

x = seq(-2.5, 2.5, length=100)

labcurve( list( One=  list( x,sin(x)), Two=  list( x,cos(x)),
   Three=list( x,(x*x)), Four= list( x,exp(x)) ),
   keys=c('1','2','3','4'),  keyloc="none", pl=TRUE )

dev.off()


Thanks for your time.
