Welcome to the Official Git Repository of ToxicR!

What is ToxicR?

ToxicR is an R package that utilizes the core functionality of the US EPA's Benchmark Dose Software and the NTP's BMDexpress, which was developed in unison with researchers from the National Institute of Environmental Health. Unlike those packages, ToxicR is fully interactive and can be used to create custom analysis pipelines within the R programming environment.

Current Release

Version 1.1.1 is the most recent release.

Installation

Depending on your system, cut and paste the following code into your R terminal.

Recommended Method

Compile Yourself

If you have the package devtools, you can download and install directly from GitHub!

library(devtools)

devtools::install_github("NIEHS/ToxicR")

Note: For Windows, you will need the rtools executable available at: https://cran.r-project.org/bin/windows/Rtools/

Note: If you have a MacOS, you will need to download the GNU Scientific Library. To do this, go to a command line and type

brew install gsl

This assumes you have HomeBrew installed. If you do not go to https://brew.sh, which will give you the instructions on how to install.

Note: For MacOS, you also need to install xcode. To do this go to the command line and type

xcode-select -install

Note: For Linux, you will also need the GNU Scientific Library. The install depends on your flavor of Linux. For Ubuntu, type

sudo apt-get install libgsl-dev

Alternative Methodology

First, install the required packages

install.packages(c("Rcpp","RcppEigen","RcppGSL","ggplot2","shiny","coda","scales","tidyverse","forcats","ggridges","doBy","multcomp","dplyr","rmarkdown", "actuar","ggpubr", "testthat","gridExtra","VIM","knitr", "modules", "plotly" ))
