In pbs-assess/PACea: An R package of Pacific ecosystem information to help facilitate an ecosystem approach to fisheries management

Points to raster nearest neighbour interpolation

Description

Points to raster nearest neighbour interpolation

Usage

point2rast(
  data,
  spatobj,
  loc = c("x", "y"),
  cellsize,
  nnmax = 4,
  as = c("SpatRast", "SpatVect")
)

Arguments

data	Vector, dataframe, or spatial (class: 'Spatial' or 'sf') input data to use for interpolation
spatobj	Spatial object used to create extent for output raster
loc	Vector of coordinate variable names or matrix of coordinates
cellsize	Output raster cell size
nnmax	Nearest neighbour maximum neighbours used for interpolation
as	Output as raster 'SpatRast' or vector 'SpatVect'

Value

A terra SpatRaster or SpatVector object

## Not run: 
dat <- data.frame(x = runif(5, 0, 10), y = runif(5, 0, 10), var = rnorm(5))
extent <- st_bbox(c(xmin = 0, ymin = 0, xmax= 10, ymax = 10),crs = NA)
output <- point2rast(dat, extent, loc = c("x","y"), cellsize = 0.5, nnmax = 2, as = "SpatRast")
output
plot(output)
