Dear,
I can't plot legend over a Rasterlayer.
My system is MAC OS Lion.
See my problem:
####### Data
> img
class : RasterLayer
dimensions : 5, 5, 25 (nrow, ncol, ncell)
resolution : 0.002245, 0.002245 (x, y)
extent : -48.33875, -48.32753, -20.35756, -20.34634 (xmin, xmax,
ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84
+towgs84=0,0,0
values : in memory
min value : 2116
max value : 36070
##### plot Rasterlayer
> plot(img, col=rev(terrain.colors(25)), axes = TRUE, xlab="x", ylab="y",
useRaster=TRUE)
Erro em as.double(y) :
cannot coerce type 'S4' to vector of type 'double'
I can plot the data with image function, but i don't know put the legend
with the color palette.
Thanks
Julio
