RRegrs

eNanoMapper Developers | [eNanoMapper Project] (http://www.enanomapper.net/)

The current tool is a collection of regression tools from R that could be used to search the best regression models for any dataset. The initial use of the script is aimed at finding QSAR models for chemoinformatics / nanotoxicology.

The full R script will contain: Loading dataset, Filter dataset, Scaling dataset, Feature selection, Regression models, Summary with top models, Statistics of the best model, etc.

The script will be modular in order to create flexible APIs.

The main authors are from the National Technical University of Athens (NTUA, Greece), Maastricht University (UM, Netherlands) and University of A Coruna (Spain).

Outputs:

• CSV files for statistics
• PDF files for plots

Install

> install.packages(c("caret", "corrplot", "data.table")) # dependencies
> install.packages("testthat") # if you want to test the package
> install.packages("devtools") # to install from GitHub
> library(devtools)
> install_github("enanomapper/RRegrs", subdir="RRegrs")

If you have errors you should try two extra parameters for install.packages such as dependencies=TRUE,repos='http://cran.us.r-project.org'.

Compile from source

$ R CMD build RRegrs
$ R CMD check --as-cran RRegrs_0.0.4.tar.gz

Caret version for RRegrs

The new version of caret is introducing some modifications that generates problems with some RRegrs methods. Therefore, RRegrs is working well with caret version 6.0.52:

• please check caret version and report to this list

> packageVersion('caret')

• remove this version and the bug

> remove.packages(c('caret'))

• install Caret Package version 6.0.52, without the bug

> library(devtools)

> install_version(package='caret',version='6.0-52')
