procAOVsym: 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

Value

• returns a dataframe containing Sums of Squares for each factor.

Details

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

## 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)
