rda: Shrunken Centroids Regularized Discriminant Analysis

Installation

The rda package was removed from CRAN (The Comprehensive R Archive Network) and is currently archived. As soon as it is back on CRAN, we will inform you that it is possible to install it from CRAN:

##    install.packages("rda")

Building from source

To install the latest stable development version from GitHub, you can pull this repository and install it using

## install.packages("remotes")
remotes::install_github("valentint/rda")

Of course, if you have already installed remotes, you can skip the first line (I have commented it out).

Example

This is a basic example which shows you if the package is properly installed:

library(rda)
data(colon)
colon.x <- t(colon.x)
(fit <- rda(colon.x, colon.y))
#> Call:
#> rda(x = colon.x, y = colon.y)
#> $nonzero
#>       delta
