[R-sig-Geo] spplot: character size of color key labels

[Oscar Perpiñan Lamigueiro]

Hi,

It seems to be a problem with sp:::fill.call.groups. 

A workaround is to use auto.key=FALSE with spplot and then update with
auto.key=list(cex=3). It works with xyplot:

p <- xyplot(a~b,data.frame(a=1:3,b=1:3,c=1:3),groups=c,auto.key=FALSE,
par.settings=custom.theme.2())
update(p, auto.key=list(cex=3))

However, although it also works with spplot, I cannot get good results
because it seems to ignore the par.settings argument, and therefore the
colors of the points inside the graphic are different from the points
of the legend. Perhaps I am missing something...

Bye,

Oscar.
