RRPP (click to expand)

The R package, RRPP, is a versatile package that performs residual randomization in a permutation procedure (RRPP) to generate sampling distributions of various linear model statistics. This package is especially useful for high-dimensional data (many variables compared to research subjects), where parametric procedures are not possible. The following are the different ways to obtain RRPP.

How to install:

devtools::install_github("mlcollyer/RRPP", build_vignettes = TRUE)

  • Github Big Data Version (an optional version that uses C++ compilation and avoids large matrix products. This version is slower but might have better memory efficiency for large data sets.)

How to install:

devtools::install_github("mlcollyer/RRPP", ref = "bigData", build_vignettes = TRUE)

Vignettes can be found here

geomorph (click to expand)

The R package, geomorph, is the most comprehensive landmark-based geometric morphometrics program, which performs virtually any analysis for landmark data (with certain exceptions). This package is maintained by Dr. Dean Adams (Iowa State University). Drs. Michael Collyer and Erica Baken (from this lab) are contributors. The package can be obtained in the following ways.

How to install:

devtools::install_github("geomorphR/geomorph", ref = "Stable", build_vignettes = TRUE)

gmShiny (click to expand)

Coming Soon!!! The Shiny app, gmShiny, is a new HTML-based app that runs many functions from the geomorph R package, in a GUI-friendly way. It was created by Dr. Erica Baken. A link will be available once it is officially released.
