[R-sig-Geo] spplot(), size of plotting symbol in legend

[karl.sommer at dpi.vic.gov.au]

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.
