In aphanotus/borealis: Tools for reproducible geometric morphometric analysis

Subset a geometric morphometric shape dataset

Description

Subset a geometric morphometric shape dataset

Usage

## S3 method for class 'gmm'
subset(A, specimens = NULL, landmarks = NULL)

Arguments

A	A geomorph.data.frame or a data structure produced by functions in the borealis package. A 3-dimensional array of XY coordinates for multiple specimens must reside in a list element called coords, gpagen$coords or gdf$coords. Associated metadata may exist in a matrix element called metadata or as vectors with a length equal to the number of specimens.
specimens	A numerical or logical vector for subsetting specimens and metadata.
landmarks	A numerical vector for subsetting landmarks. Subsetting landmarks will not affect metadata.
