procAOVsym: Procrustes ANOVA for structures with object symmetry

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

Procrustes ANOVA for structures with object symmetry

Description

Procrustes ANOVA for structures with object symmetry, currently only supporting the factors 'specimen', 'side' and the interaction term.

Usage

procAOVsym(symproc, indnames = NULL)

Arguments

symproc	object returned by procSym, where pairedLM is specified
indnames	vector containing specimen identifiers. Only necessary, if data does not contain dimnames containing identifiers

Details

performs a Procrustes ANOVA for configurations with object symmetry (as described in Klingenberg et al. 2002).

Value

returns a dataframe containing Sums of Squares for each factor.

Note

In future releases the implementation of support for bilateral symmetry and more factors is intended.

Examples

data(boneData)
left <- c(4,6,8)
## determine corresponding Landmarks on the right side:
# important: keep same order
right <- c(3,5,7)
pairedLM <- cbind(left,right)
symproc <- procSym(boneLM, pairedLM=pairedLM)
procAOVsym(symproc)
