This package is still under development.

Installation

You can install it using the devtools package:

devtools::install_github("pierreroudier/spemd")

If you do not have the devtools package installed, you can install it simply using:

install.packages("devtools")

Quick example

Gridded data

library(spemd)

library(gstat) # to get sample data
library(raster) # for visualisation

# Load sample data
data(ncp.grid, package = 'gstat')
coordinates(ncp.grid) <- ~x+y
gridded(ncp.grid) <- TRUE

plot(raster(ncp.grid))

# Run EMD
res.ncp <- spEMD(ncp.grid, zcol = "depth", thresh.extrema = 0.1, verbose = FALSE)

# Plot results
res <- stack(res.ncp)
plot(res)
