Description

An S4 Class for Functional Data.

S4 classes for univariate and multivariate functional data with utility functions. See <doi:10.18637/jss.v093.i05> for a detailed description of the package functionalities and its interplay with the MFPCA package for multivariate functional principal component analysis <https://CRAN.R-project.org/package=MFPCA>.

AppVeyor Build Status CRAN_Status_Badge Coverage Status

funData is an R-package that allows users to easily handle functional data. The data is stored in an object-oriented manner using S4 classes and methods.

Highlights

funData provides a unified framework for different types of functional data:

  • Univariate and multivariate data
  • Regularly and irregularly sampled data
  • Data with one-, two- (images) and even higher-dimensional domains

Important functionalities include:

  • Displaying, Plotting, including an interface to ggplot2
  • Subsetting (samples, domain)
  • Basic arithmetics and averaging
  • Integration over the domain
  • A fully integrated simulation toolbox

Installation

The funData package is available on CRAN. To install the latest version directly from Github, please use devtools::install_github("ClaraHapp/funData") (install devtools before).

Dependencies

The funData package depends on the R-packages fields, foreach, abind and methods.
