morph_nds_group: Morphometrics classification between GUs

In zoometh/iconr: Graphical and Spatial Analysis for Prehistoric Iconography

Morphometrics classification between GUs

Description

Momocs package morphometrics classification (groups) between different graphical units (GUs). Read JPG files from each different folder. Useful after comparisons (see, 'morph_nds_compar' function)

Usage

morph_nds_group(
  nodes = NA,
  gu.types = "all",
  focus = c("kmeans"),
  nb.h = 15,
  nb.centers = 1,
  cex = 4,
  lwd = 1.5,
  dataDir = system.file("extdata", package = "iconr"),
  out.dir = "_out",
  out.data = c("mbrshp", "plot"),
  verbose = TRUE
)

Arguments

nodes	Dataframe of nodes.
gu.types	Classes of nodes that will be clustered, a vector of characters or a character. By default "all".
focus	Type of grouping, Kmeans ("kmeans"). By default, c("kmeans").
nb.h	Number of Fourier harmonics, uniquely for PCA. By default = 15.
nb.centers	Number of clusters, uniquely for Kmeans. By default 1 (unique cluster).
cex	Size of the text, by default 1.
lwd	Width of the dendrogram branches, by defaul 1.
dataDir	Path to the folder.
out.dir	Name of output folder.
out.data	Type of data returned. If "mbrshp" return a dataframe of nodes with their clustering and image path. If "plot" return a "kmeans" or create a plot. By default c("mbrshp", "plot").
verbose	if TRUE (by default), verbose.

Value

Depending on the focus, creates plots (ex: Kmeans ("kmeans")), print their complete paths, return the Kmeans membership in a dataframe.
