I wanted to visualize a land cover dataset that comes with a specific color table. When using plot(), each class is plotted in the color specified in this table. However, the legend seems to be missing.
I executed the code from the color table help page and had the same problem.
r <- rast(ncols=3, nrows=2, vals=1:6)
coltb <- data.frame(value=1:6, col=rainbow(6, end=.9))
plot(r)
gives the regular plot including the legend: Image link
But after doing
coltab(r) <- coltb
plot(r)
I get a plot without legend: Image link
Am I missing something here? Do I need to supply the plot() function with an additional argument? How can I work around this in the easiest way? Setting a color table for a SpatRaster with coltab() is a nice feature but not of much use if the legend is not plotted.
