spplot(), size of plotting symbol in legend

Hi Edzer,

your suggestion worked well.  I saved the plot as an object named z1. In
the legend variable I found the settings for symbol size. In my case there
were 4 entries which I changed from 0.1 to 1
using the following statement.

z1$legend$inside$args$key$points$cex <- c(1,1,1,1)
plot(z1)

Regards

Karl

Karl, I don't see an easy way for this, except by changing the code.
Perhaps you could save the object the spplot returns (spplot basically
wraps xyplot), and go in there.

Hello list,

I was wondering if it were possible in spplot() to influence the size of
the plotting symbol appearing in the legend independently of the size of
the plotting symbol in the graph.
I have a situation where the symbol in the graph needs to be very small,
i.e. cex=0.1.  Consequently, the symbol appearing in the legend becomes
almost illegible. I need to make it bigger, independently of the symbol
size in the graph.

Thanks

Karl
