Please ensure that it is really the exact same code, I'm sure you did
not mean to plot "f", but "r" (for example).
Also, sessionInfo results are helpful always - see the posting guide
for ways to post better questions.
Loading required package: sp
raster version 1.9-5 (28-July-2011)
> f <- system.file("external/test.grd", package="raster")
> r <- raster(f)
Here is "f" - not "r"! And the error here is to be expected since f
is just a character string.
Error in plot.window(...) : need finite 'ylim' values
In addition: Warning messages:
1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
2: In min(x) : no non-missing arguments to min; returning Inf
3: In max(x) : no non-missing arguments to max; returning -Inf
