Unable to find an inherited method for function ‘mask’ #74

Closed lrose1 closed 3 years ago

Hello, I am getting an error that I cannot figure out. The error message seems quite vague:

Input: `library(Rnightlights) pkgOptions(downloadMethod = "aria", cropMaskMethod = "gdal", extractMethod = "gdal", deleteTiles = TRUE)

ctry <- "HUN" #replace to run for any other country

Hi,

This may be due to some changes that have happened in other packages especially around the gdal-based implementation. Let me run the same commandline and see what might be happening. Meanwhile, you can try to run it without gdal by changing the pkgOptions. So either don't set cropMaskMethod and extractMethod so they use the default (rast) or instead of gdal set them to "rast".

cropMaskMethod = "rast", extractMethod = "rast"
