We provide here a R package which combine multiple Feature Selection (FS) methods in a workflow for analizing high-dimentional omics data. The different feature selection steps can be classificated in: i) Univariate (Correlation filter and Gain Information), ii) Multivariate (Principal Component Analysis and Matrix Correlation based) and iii) Recursive Feature Elimination (wrapped up with a Machine Learning algorithm, e.g. Random Forest). The goal is to essemble the different steps in an efficient workflow to perform feature selection in the contex of classification and regression problems.
The first step is to install devtools:
install.packages("devtools")
library(devtools)
Then, we can install the package using:
install_github("enriquea/feseR")
library(feseR)
We provide here some examples for illustrating how to use the package.
