[R] plotting rasters - no plot, no error

[Monica Pisica]

Hi Mike,


Very interesting. The plot itself on the computer that does not plot - still does not plot - no surprise there. But the command with useRaster = FALSE actually plots the raster. So that means it is something wrong with the raster package? Did i forget to install some dependency, although i though i ask for all to be installed?


I still don't know how to solve the problem, but thanks so much for an alternative way to actually plot my rasters.


Monica
