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.

• CRAN Version  (Installed through R)

• Github Version

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)

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.

• CRAN Version  (Installed through R)

• Github Version

How to install:

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