⚠️There's a newer version (4.0.8) of this package.Take me there.

geomorph

Geomorph is a software package for performing all stages of geometric morphometric shape analysis of 2- and 3-dimensional landmark points, as well as semilandmarks on curves and surfaces, in the R statistical computing environment. This repository is dedicated to providing beta versions between CRAN uploads.

Details of the installion can be found here: https://github.com/geomorphR/geomorph/wiki/Installing-geomorph .

Details on how to get started can be found on the geomorph wiki: https://github.com/geomorphR/geomorph/wiki .

To install the current geomorph R-package from CRAN:

Within R:

install.packages("geomorph")

To install the current version of geomorph R-package from Github using devtools:

Within R:

install.packages("devtools")

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

This installs a stable release of the current version of geomorph on CRAN, allowing us to quickly fix errors that slip thorugh the cracks and are uploaded with the CRAN version.

To install the Development version (beta) of geomorph R-package from Github using devtools:

Within R:

install.packages("devtools")

devtools::install_github("geomorphR/geomorph",ref = "Develop")

NOTE FOR THE PRE-RELEASE (BETA) VERSION: We strongly discourage you from publishing results with this version, unless you check with the authors first.
