R software: the minimal requirement is R version 3.5.1.
R packages (it is recommended if the most recent versions of the following packages are installed):
devtools
, for developing utilities and interfaces with on-line repositories;To install the required packages, the following R code should be executed before the installation:
pkgnames <- "devtools"
pkgnames <- pkgnames[!pkgnames %in% .packages(TRUE)]
if (length(pkgnames)) install.packages(pkgnames)

On Windows, by opening the command prompt (cmd.exe
), it is possible to point to the proper directory with cd
, and then install the package via Rcmd.exe
with the following command:
Rcmd.exe INSTALL plpoisson_0.3.1.tar.gz
