[R] legend position

[David Carlson]

It is not straightforward unless you want the legend in the
right or the bottom margins. To put the legend inside the plot
region it is simplest to use image() to plot the raster file and
then image.plot(legend.only=TRUE) to add the legend. In addition
to reading the help page for plot{raster}, you also need the
pages for image{raster} and image.plot{fields}. Here are two
simple examples.

image(r,  col=rev(terrain.colors(255)))
plot(r, horizontal=TRUE, smallplot=c(.15, .5, .84, .86),
legend.only=TRUE)

image(r,  col=rev(terrain.colors(255)))
plot(r, smallplot=c(.15, .17, .5, .85), legend.only=TRUE)

Subject: [R] legend position

Hi all. 
I'm ploting a raster and I can't find the proper way to move the
legend. For example,
r = raster(system.file("external/test.grd",
package="raster"))plot(r)
How can I put the legend at the desired position?
Thank in advance,Phil
