move {red} | R Documentation |
Move records to closest non-NA cell.
Description
Identifies and moves presence records to cells with environmental values.
Usage
move(longlat, layers, buffer = 0)
Arguments
longlat |
Matrix of longitude and latitude or eastness and northness (two columns in this order) of species occurrence records. |
layers |
SpatRaster* object as defined by package raster. |
buffer |
Maximum distance in map units that a record will move. If 0 all NA records will be changed. |
Details
Often records are in coastal or other areas for which no environmental data is available. This function moves such records to the closest cells with data so that no information is lost during modelling.
Value
A matrix with new coordinate values.
Examples
rast <- terra::rast(matrix(c(rep(NA,100), rep(1,100), rep(NA,100)), ncol = 15))
pts <- cbind(runif(100, 0, 5), runif(100, 0, 15))
terra::plot(rast)
points(pts)
pts <- move(pts, rast)
terra::plot(rast)
points(pts)
