simple spplot problem (colorkey inside the plotting area)

I'm using spplot to color regions of Austria
Everything works fine
But I like to have the colorkey INSIDE the plotting area (in the Bavaria
window :-)

space just puts it outside (top, bottom, left, right)

as the spplot is a lattice object it should be possible

I've tried the examples from http://r-spatial.sourceforge.net/gallery/
With the key.space=list(x=0.2,y=0.9,corner=c(0,1))
But this is simply ignored

Is there a way to do this (without using a lattice layer and rebuilding
the colorkey ;-)

I'm using R  2.12.2
Package sp version 0.9-78

Every help would be welcome

Hi Rainer,

I'm not sure whether I can help, but as soon as I include a
"key.space=list(x=0, y=0, corner=c(0,0))" into an spplot call, the color
key wanders into the plotting rectangle. The (minimal) full call here is:

print(spplot(sppdf, zcol = i, key.space=list(x=0,y=0.01,corner=c(0,0))))

(inside the postscript device for producing eps figures)

If you have, maybe post some code that we can try; or the structure of
your data frame and some further lines to experiment with.

Hy Georg 
For me it does not work

Here s the Code

# Rdata from http://gadm.org/countryies for Austria Bundesl?nder
load("AUT_adm1.RData")
library(sp)
library(RColorBrewer)
#percent per Bundesland in the correct order
proznormal09=c(3.76,6.57,24.52,18.05,6.59,13.94,6.91,3.74,15.91)
#produce factor
 bundeslfakt <- as.factor(as.numeric(cut(proznormal09, c(0,4,7,10,13,16,19,100)))
levels(bundeslfakt) <- c("<4%", "4-7%", "13-16%", "16-19%",">19%")
gadm$bundeslfakt <-bundeslfakt
#the plot
spplot(gadm, "bundeslfakt", col.regions=brewer.pal(5,"Reds"), main="Prozentverteilung nach Herkunftsbundesl\u00E4nder",key.space=list(x=0,y=0,corner=c(0,0)))

produces a plot with the colorkey on the right side
key.space is ignored

I hope you can reproduce the Effect ;-)
or tell me where I went wrong

Dear Rainer,

spplot is a wrapper function around levelplot (for grids, polygons and
lines) or xyplot (for points), both in package lattice.

As the documentation mentions, the key.space argument is only available
for points, where it is passed (as key argument) to xyplot.

I looked up the documentation of ?levelplot (after loading lattice), and
although it does have x and y componenents for the colorkey, it does
explicitly mention that these are not implemented. The only things you
can modify are the key height/width, and the space argument ('bottom',
'left', 'right', 'top'). I do not see a possibility to move the key to
wherever you want.

I cc:'d this message to Deepayan Sarkar, the lattice author, maybe he
has a suggestion where to look next.
