Today's exercise is nice and simple, and allows you to get used to manipulating datasets in R.Exercise 2 - How to delete specimens or landmarks from a dataset of morphometric data (shape data).When you load your shape data into R with Geomorph (with th... [Read more...]

I thought it would be helpful to new users of Geomorph and R to discuss some tips and tricks for manipulating morphometric datasets in R. So I am starting a series called "Tips & Tricks". These will be published as I think of them, and assume you h... [Read more...]

Happy New Year to all Geomorph users,I have received a few emails from Mac users wanting to update to the new version of Geomorph. Unfortunately there is still a lag on the CRAN repository for a MacOS X binary of version 1.1-5. While this is a nuisance... [Read more...]

Geomorph users,We have uploaded version 1.1-5 to CRAN. The windows binary has been compiled and the tarball is available. The MAC OSX binary may take a few days (mac users can install the package from source using the tar.gz file). The PDF of helpfiles has not yet been ... [Read more...]
