Description Usage Arguments Examples

Description

Evaluate whether two SpatRaster objects have the same extent, number of rows and columns, projection, resolution, and origin (or a subset of these comparisons).

## S4 method for signature 'SpatRaster,SpatRaster'
compareGeom(x, y, ..., lyrs=FALSE, 
          crs=TRUE, warncrs=FALSE, ext=TRUE, rowcol=TRUE, res=FALSE)

Arguments

x

SpatRaster

y

SpatRaster

...

Additional SpatRasters

lyrs

logical. If TRUE, the number of layers is compared

crs

logical. If TRUE, coordinate reference systems are compared

warncrs

logical. If TRUE, a warning is given if the crs is different (instead of an error)

ext

logical. If TRUE, bounding boxes are compared

rowcol

logical. If TRUE, number of rows and columns of the objects are compared

res

logical. If TRUE, resolutions are compared (redundant when checking extent and rowcol)
