Update of Morpho and related publications

It has been some time since my last post, so here a quick update. Last month, I have issued a new release of Morpho (2.6) on CRAN that contains a lot of new features. As it happens, we managed to get two new papers published that directly relate to some ofthose new features.

The first paper ist on extracting parts of a triangular mesh based on its visibility from a set of view points.

The second paper deals with retrodeforming fossil specimens with an emphasis on symmetrically placed semi-landmarks.

2. Schlager S, Profico A, Di Vincenzo F, Manzi G. 2018. Retrodeformation of fossil specimens based on 3D bilateral semi-landmarks: Implementation in the R package “Morpho”. PLOS ONE 13(3):1–19.

Here is the complete list of changes in the latest Morpho (2.6) release

Morpho

New features

• virtualMeshScan, getOuterViewpoints: perform a virtual rescan of a mesh using defined POVs.
• deformGrid3d: fixed indices starting with 0 for slices, add gridcol and gridwidth and added options to select subsets of slices.
• deformGrid2d: added options cex1,cex2,gridcol
• fixLMmirror: now allowing heavy abuse with loads of missing data and improved error handling
• plotNormals: allow for per vertex lenght vector and changed long=>length and deprecated old option
• checkLM: added possibility to view backwards
• slider3d: made function work in parallel on all OS
• pls2B: added CV (+ options)
• added plsCoVarCommonShape: Compute the shape changes along the common axis of deformations
• added getPLSCommonShape: Obtain linear combinations associated with the common shape change in each latent dimension of a pls2B

Bugfixes and minor changes

• line2plane: fixed deprectated array multiplication warning
• changed Matrix::cBind to base::cbind
• Depend: > R 3.2.0
• GetPhi (privat function in retrodeform3d): set h to average between landmark distance (not the squared distance)
• CVA: add rownames and colnames to scores and CVs
