Usage

2
phylocurve.trim(phylocurve.generalized, min_Y = -Inf,
  max_Y = Inf, min_X = -Inf, max_X = Inf)

Arguments

phylocurve.generalized

The value returned by the phylocurve.generalized function

min_Y

The minimum Y value for trimming curves

max_Y

The maximum Y value for trimming curves

min_X

The minimum X value for trimming curves

max_X

The maximum X value for trimming curves

Value

aligned_data

x and y coordinates arranged in a single row vector for each species

aligned_coordinates

x and y coordinates for each species (one data point per row)

aligned_X

Aligned X coordinates in N x M matrix

aligned_Y

Aligned Y coordinates in N x M matrix

nr

Number of aligned landmarks

anc_X

Vector of root X values (assuming Brownian motion)

anc_Y

Vector of root Y values (assuming Brownian motion)

tree

Phylogenetic tree supplied into the function
