Colleagues, I'm pleased to announce that geomorph 3.1.1 is now available on CRAN. As always, all changes are noted in the NEWS file and in the appropriate help pages. To install geomorph 3.1.1 from within R, simply type:
install.packages('geomorph') We wish to emphasize that this was a rather substantial update; thus, users are highly encouraged to consult all help files for additional information. Though some functions have been deprecated, all analyses previously available in geomorph are still available (though some more advanced options are now accessed in slightly modified form). Also, to ease users through this transition, we have developed a vignette that describes the differences in the current version, and how to implement various analyses using the newer notation. The vignette is distributed with the installation of geomorph, and may be accessed by typing: browseVignettes(package="geomorph") In particular, users will notice a change in usage of the 'procD' family of functions for assessing linear models. Beginning with geomorph 3.1.1, only 'procD.lm' and 'procD.pgls' remain, and these have greatly enhanced functionality. For instance, one may now utilize type I, type II, or type III sums of squares, may specify the error term against which various factors are evaluated (to incorporate random effects in simple mixed model designs), and may incorporate object-covariance matrices describing non-independence. Additionally, pairwise comparisons of means, of slopes, and of within-group variation may be accomplished using the 'pairwise' function based off of fitted models from 'procD.lm' or 'procD.pgls'. The functions: procD.allometry, advanced.procD.lm, and nested.update, have all been deprecated, as their analyses are now accomplished (and enhanced) via these other functions. These enhancements were made possible by use of the RRPP package (Collyer and Adams, 2018: Methods Ecol. Evol) which is now more tightly interconnected with geomorph. Finally, for graphical visualization of shapes, we encourage users to explore the new picknplot.shapes function, which allows one to select locations from just about any kind of plot obtained in geomorph, and generate estimates of shapes that correspond to those locations (much like in the TPS series). Also, the new plotAllometry function provides several graphical plots commonly used in allometric studies. We hope these new graphical options provide additional flexibility and usability of geomorph. Best to all, Dean, Mike, and Antigoni (the geomorph team) Dr. Dean C.
