Install mlxR

To use mlxR you first need to install the Mlxlibrary (a component of the Monolix Suite 2016R1) from here


Then you can either

        - install mlxR 3.2 from CRAN as a source package:

install.packages("mlxR", type = "source")
library("mlxR")


        - install the development version of mlxR from GitHub:

devtools::install_github("MarcLavielle/mlxR")
library("mlxR")

See the release notes for more details on the current versions of mlxR on CRAN and GitHub.
