get_unique_values

Description

This function returns the unique values of an object.

Usage

get_unique_values(x, simplify, verbose)

## S3 method for class 'numeric'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'matrix'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'RasterLayer'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'list'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'RasterStack'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'RasterBrick'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

## S3 method for class 'stars'
get_unique_values(x, simplify = FALSE, verbose = TRUE)

Arguments

x

vector, matrix or Raster* object
simplify

If true, a vector will be returned instead of a list for 1-dimensional input
verbose

If true, warning messages are printend

Details

Fast and memory friendly Rcpp implementation to find the unique values of an object.

Examples

get_unique_values(landscape)

landscape_stack <- raster::stack(landscape, landscape, landscape)
get_unique_values(landscape_stack)

landscape_matrix <- raster::as.matrix(landscape)
get_unique_values(landscape_matrix)

x_vec <- c(1, 2, 1, 1, 2, 2)
get_unique_values(x_vec)

landscape_list <- list(landscape, landscape_matrix, x_vec)
get_unique_values(landscape_list)
