rasterizeReduced: Convert reduced representation to full raster

Description

Convert reduced representation to full raster

Usage

rasterizeReduced(reduced, fullRaster, plotCol, mapcode = names(fullRaster), ...)

Arguments

reduced
data.frame or data.table that has at least one column of codes that are represented in the fullRaster.
fullRaster
RasterLayer of codes used in reduced that represents a spatial representation of the data
plotCol
a character, length 1, with the name of the column in reduced that whose value will be plotted
mapcode
a character, length 1, with the name of the column in reduced that is represented in fullRaster
...
Other arguments. None used yet.

Value

A RasterLayer of with same dimensions as fullRaster representing plotCol spatially, according to the join between the mapcodeAll contained within reduced and fullRaster

Examples

Run this code
library(data.table)
library(raster)
Ras <- raster(extent(0,15,0,15), res=1)
fullRas <- randomPolygons(Ras, numTypes=2)
names(fullRas) <- "mapcodeAll"
uniqueComms <- unique(fullRas)
reducedDT <- data.table(mapcodeAll=uniqueComms,
   communities=sample(1:1000,length(uniqueComms)),
   biomass=rnbinom(length(uniqueComms),mu=4000,0.4))
biomass <- rasterizeReduced(reducedDT, fullRas, "biomass")

# The default key is the layer name of the fullRas, so even
# if the reducedDT is miskeyed
setkey(reducedDT, biomass)

communities <- rasterizeReduced(reducedDT, fullRas, "communities")
setColors(communities) <- c("blue", "orange", "red")
if (interactive()) Plot(biomass, communities, fullRas, new = TRUE)
