The package is now available on CRAN:
install.packages("spemd")
Alternatively, you can install the development version 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")
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)
