This package implements distance based generalized sensitivity analysis method (DGSA). For more information about the method please read:

You can install the package manually or from GitHub:
Clone to your own computer, open Rstudio or R and type:
install.packages("package_Location", repos = NULL, type=source)You also have an option to load your clone as a project in Rstudio and then proceed with project build Ctrl+Shift+B. This is particularly useful if you plan on adding/modifying features.
First you will need to make sure that you have devtools installed, then you can install
with the following command:
devtools::install_github("ogru/DGSA")After that you can proceed to load the routines in the usual way with library(DGSA).
To view some of the package capabilities go to the following link:
https://rawgit.com/ogru/DGSA/master/vignette/Intro_to_DGSA.html
It will view the vignette without downloading the package/file.
If you prefer to work with MATLAB, you can find the original MATLAB implementation here: https://github.com/scheidtc/dGSA. However, without the matrix plot for visualization of all sensitivities/importances.
