sort function

Sort a SpatRaster or SpatVector

Sort the cell values of a SpatRaster across layers. You can also compute the sorting order.

Or sort the records of SpatVector (or data.frame) by specifying the column number(s) or names(s) to sort on. methods

## S4 method for signature 'SpatRaster'
sort(x, decreasing=FALSE, order=FALSE, filename="", ...)

## S4 method for signature 'SpatVector'
sort(x, v, decreasing=FALSE)

Arguments

• x: SpatRaster
• decreasing: logical. If TRUE, sorting is in decreasing order
• order: logical. If TRUE the sorting order is returned instead of the sorted values
• filename: character. Output filename
• ...: additional arguments for writing files as in writeRaster
• v: character or numeric indicating the column(s) to sort on

Returns

SpatRaster

Examples

f <- system.file("ex/elev.tif", package="terra")
r <- rast(f)
r <- c(r, r/2, r*2)
sort(r)

ord <- sort(r, order=TRUE)
# these two are the same 
ord[[1]]
which.min(r)
