Description

Trip rasterize.

Arguments

x	trip object
y	Raster* object
field	attribute from which differences will be calculated, defaults to the time-stamp between trip locations

Value

RasterLayer

Examples

 d <- data.frame(x=1:10, y=rnorm(10), tms=Sys.time() + 1:10, id=gl(2, 5))
tr <- trip(d, c("tms", "id"))

tr$temp <- sort(runif(nrow(tr)))
r <- rasterize(tr)

rasterize(tr, grid = r)

rasterize(tr, r, field = "temp")
rasterize(tr, method = "density")
rasterize(tr, method = "density", grid = r)

rasterize(tr, r, field = "tms")
rasterize(tr, r)
