Compute the area covered by polygons
Usage
# S4 method for class 'giottoPolygon'
expanse(x, output = c("data.table", "named", "vector"), ...)
# S4 method for class 'giottoPolygon'
area(x, ...)Arguments
- x
giottoPolygon- output
one of
"data.table"(default),"named", or"vector"."data.table"returns adata.tablewith columnscell_IDandarea."named"returns a named numeric vector withcell_IDas names."vector"returns a plain unnamed numeric vector (terra-compatible).- ...
Arguments passed on to
terra::expanseunitcharacter. Output unit of area. One of "m", "km", or "ha"
transformlogical. If
TRUE, planar CRS are transformed to lon/lat for accuracybyValuelogical. If
TRUE, the area for each unique cell value is returnedzonesNULL or SpatRaster with the same geometry identifying zones in
xwidelogical. Should the results be in "wide" rather than "long" format?
usenameslogical. If
TRUElayers are identified by their names instead of their numbers
Details
Giotto's expanse() method dispatches on terra's generic. When the
underlying data is a SpatVector, transform defaults to FALSE and
CRS warnings are suppressed — both appropriate for biological coordinate
systems. When the underlying data is a non-terra representation (e.g. a
disk-backed store), the call is forwarded to a method for that class.
Examples
sl <- GiottoData::loadSubObjectMini("spatLocsObj")
gpoly <- GiottoData::loadSubObjectMini("giottoPolygon")
gpoints <- GiottoData::loadSubObjectMini("giottoPoints")
