Download the latest 52n WPS release from here.(If you want the source code, follow this tutorial)
Rename the downloaded .war file to wps.war and drop it in the webapps folder of your tomcat.

Configure R

Start R, install the package Rserve and the recommended ones with the following command. Add more of them for your own purposes:

install.packages(c("Rserve","sp","maptools","rgdal", "spatstat","gstat","automap"))

Optional

You can use the Rprofile.site file in directory R_HOME%/etc to configure options and packages that should be available on every start of R. To do this, initialize the .First function. Specify required libraries and the default work directory inside the function. These settings will be preloaded during start-up of R:

.First <- function() {
#the following libraries will be loaded on R start-up:
library(sp)
library(gstat)
library(rgdal)
library(spatstat)
library(maptools)
library(automap)
#specify the R work directory here:
setwd("<R WD>")
}
