Readme

rchemo - Dimension reduction, Regression and Discrimination for Chemometrics

rchemo is a package for data exploration and prediction with focus on high dimensional data and chemometrics.

The package was initially designed about partial least squares regression and discrimination models and variants, in particular locally weighted PLS models (LWPLS) (e.g. https://doi.org/10.1002/cem.3209). Then, it has been expanded to many other methods for analyzing high dimensional data.

The name rchemo comes from the fact that the package is orientated to chemometrics, but most of the provided methods are fully generic to other domains.

Functions such as transform, predict, coef and summary are available. Tuning the predictive models is facilitated by generic functions gridscore (validation dataset) and gridcv (cross-validation). Faster versions are also available for models based on latent variables (LVs) (gridscorelv and gridcvlv) and ridge regularization (gridscorelb and gridcvlb).

All the functions have a help page with a documented example.

NOTE: This repository replaces the previous rchemo repository that now is archived.

Installation

Using Rstudio is recommended for installation and usage.

rchemo can be installed from the official R repo CRAN.

It can also be installed from the Chemouse Github repo using the following steps:

1. Install package 'remotes' from CRAN

Use the Rstudio menu

or write in the R console {r} install.packages("remotes")

2. Install package 'rchemo'

a) Most recent version

Write in the R console {r} remotes::install_github("ChemHouse-group/rchemo", dependencies = TRUE) In case of the following question during installation process: {r} These packages have more recent versions available. Which would you like to update?" it is recommended to skip updates (usually choice 3 = None)

b) Any given tagged version

e.g. with tag "v0.1-1", write in the R console {r} remotes::install_github("ChemHouse-group/rchemo@v0.1-1", dependencies = TRUE)

Usage

Write in the R console {r} library(rchemo)
