cfda provides functions for the analysis of categorical functional data.

The main contribution is the computation of an optimal encoding (real functional variable) of each state of the categorical functional data.

## Installation

From CRAN:

install.packages("cfda")

From github:

library(remotes)
install_github("modal-inria/cfda", build_vignettes = TRUE)

## Vignette

Once the package is installed, a vignette describing the mathematical background and showing an example is available using the R command:

RShowDoc("cfda", package = "cfda")

## Credits

cfda is developed by Cristian Preda (Inria Lille, Université de Lille), Quentin Grimonprez (Inria Lille) and Vincent Vandewalle (Inria Lille, Université de Lille).
