compareGeom: Compare geometries of SpatRasters

compareGeomR Documentation

Compare geometries of SpatRasters

Description

Evaluate whether two SpatRasters have the same extent, number of rows and columns, projection, resolution, and origin (or a subset of these comparisons). Or whether two SpatVectors have the same geometries, or whether a SpatVector has duplicated geometries.

Usage

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

## S4 method for signature 'SpatVector,SpatVector'
compareGeom(x, y, tolerance=0)

## S4 method for signature 'SpatVector,missing'
compareGeom(x, y, tolerance=0)

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)

stopOnError

logical. If TRUE, code execution stops if raster do not match

messages

logical. If TRUE, warning/error messages are printed even if stopOnError=FALSE

tolerance

numeric

Value

logical (SpatRaster) or matrix of logical (SpatVector)

Examples

r1 <- rast()
r2 <- rast()
r3 <- rast()
compareGeom(r1, r2, r3)
nrow(r3) <- 10


## Not run: 
compareGeom(r1, r3)
