New CRAN-Releases of Morpho and Rvcg

02 Jul 2015

Within the last weeks, I finally managed to update my official R-packages Morpho and Rvcg on CRAN.

The changes are:

added function line2plane to calculate intersection of a line and a plane
added option pcAlign in function mirror to improve alignment to original object
added option pcAlign in relWarps and procSym to allow alignment to first specimen rather than PC-axes.
Gregory Jefferis added unit testing setup infrastructure
added new functions getPLSfromScores, getPLSscores, predictPLSfromScores,predictPLSfromData and plsCoVar for prediction and handling results from 2-Block PLS regression.
made relaxLM an S3 function and added methods for mesh3d to relax two meshes with corresponding vertices. Added use.lm to specify subset of coordinates for alignment if bending=FALSE
new option ‘as.factor’ in name2factor
deprecated warp.mesh (use tps3d now for meshes and matrices)
meshDist now allows custom colorramps
added option wireframe in deformGrid2d
added support for registered meshes in computeTransform
added selection of transform type in icpmat
added option use.lm to slider3d to specify subset for alignment if bending=FALSE
added getMeaningfulPCs to determine meaningful Principal Components (see my post here)
made optimization in pcAlign and mirror run in parallel (not supported on Windows OS).

fixed normal handling inmergeMeshes
fixed coefficient scaling in RegScore
added update of normals in meshDist
removed unnecessary function meanMat and replaced it with generic colMeans
fixed calculation of loadings in pls2B
set lambda (regularization) in all tps related functions to 1e-8 to avoid gross distortions in some cases
fixed typo in pcAlign leading to misbehavior if iterations < 1
