rangeFill: Fill layers with a range

In terra: Spatial Data Analysis

Fill layers with a range

Description

Fill layers with cell-varying ranges defined by a start and end SpatRaster. The range must start at 1 and end at a user-defined maximum.

For example, for a cell with start=3, end=5 and with limit=8, the output for that cell would be 0,0,1,1,1,0,0,0

Usage

## S4 method for signature 'SpatRaster'
rangeFill(x, limit, circular=FALSE, filename="", ...) 

Arguments

x	SpatRaster with at two layers. The Cell values of the first layer indicate the start of the range (1 based); the cell values are indicate the end of the range
limit	numeric > 1. The range size
circular	logical. If TRUE the values are considered circular, such as the days of the year. In that case, if first > last the layers used are c(first:limit, 1:last). Otherwise, the range would be considered invalid and NA would be used
filename	character. Output filename
...	additional arguments for writing files as in writeRaster

Value

SpatRaster

Examples

x <- y <- rast(ncol=2, nrow=2)
values(x) <- c(NA, 1:3)
values(y) <- c(NA, 4:6)

r <- rangeFill(c(x, y), 8)
