Hi all,
I need to produce two different spplot figures of spatial points, and I
would like to ask your help for the creation of the second one:
1) the first figure has to show the values but without any legend:
library(sp)
xyz = data.frame(expand.grid(x=1:10,y=1:10),rnorm(100))
coordinates(xyz)=~x+y
spplot(xyz, cex=10, alpha=0.7, auto.key=FALSE)
(I don't have any problem with this)
2) The second figure has to show ONLY the legend for the values of the
previous figure (without plotting the points), inside the plotting area.
I tried with:
spplot(xyz, cex=0, alpha=0.7, auto.key=TRUE, key.space="center")
but it doesn't work.
I know that "center" is not a valid argument for 'key.space', but I
don't figure out how to produce this second figure.
I would really appreciate any help with this.
Thanks in advance,
Mauricio Zambrano-Bigiarni
