morphospace: Build morphological space

In jiho/morphr: Analyse the Morphology of Objects on Images

Build morphological space

Description

Build a morphological space by performing dimensionality reduction on a table of morphological descriptors.

Usage

morphospace(x, weights = NULL, method = "PCA", ...)

Arguments

x	data.frame or matrix of morphological descriptors. Should be all numeric and as close to normally-distributed as possible.
weights	vector of objects weights, with no weights by default. Should have as many elements as rows in x but they do not need to sum to 1.
method	dimensionality reduction method. Currently only "PCA" is implemented (with FactoMineR::PCA()).
...	passed to the dimensionality reduction function.

Value

An object of class morphospace.

Examples

s <- morphospace(plank[,-(1:2)], weights=plank$conc)
plot(s, choix="ind")
plot(s, choix="var")
