R packages

itsadug

We've combined several functions that facilitate the statistical analysis with GAMMs in the package itsadug, which is available on CRAN. The package includes functions for model comparisons, visualization of nonlinear interactions, and inspection of the residuals.

Version 2.3 of itsadug is available on CRAN. Below the code for installing the newest version of itsadug (version 2.3) directly.

how to install:

If you are interested to try the package, you can use the package installer in R, or run the following code in R to install the package:

install.packages("itsadug")

Alternatively, the newest version of the package can be downloaded or directly installed from my website. Run the following code in R:

# first install the package plotfunctions (necessary for itsadug):

install.packages("http://www.jacolienvanrij.com/itsadug/package/plotfunctions_1.3.tar.gz", repos=NULL, type="source")

# then install itsadug in the same way:

install.packages("http://www.jacolienvanrij.com/itsadug/package/itsadug_2.3.tar.gz", repos=NULL, type="source")


plotfunctions

The package plotfunctions implements various functions that facilitate visualization of data and analysis results. The functions in the package are relatively simple and are intended to facilitate incremental building of graphs using the standard R plot functions (e.g., plot, lines, points) An overview of most functions can be found in the vignette (or see vignette("plotfunctions") ).
