In johnlpearce/sommix: Tools to Apply Self-Organizing Maps

Description

Plots SOM profiles using radial segment diagrams

Usage

sommix_star(
  som_obj,
  varnames = NULL,
  colormod = NULL,
  nodelab = TRUE,
  labtype = "IDs",
  labsize = 1,
  addFreq = FALSE,
  freqtype = "frq",
  freqsize = 1,
  legsymsize = 2,
  leglabsize = 1,
  legtxtlas = 2
)

Arguments

som_obj	a SOM object
varnames	specifies variable names
colormod	can be used to customize plot color schemes. The default is terrain.colors().
nodelab	whether or not to display reference labels aon each node
labtype	determines type of node referencing to display. "IDs" and "XYs" are available
labsize	sets size of node labels
addFreq	whether or not to display frequency labels
freqtype	determines type of frequency labels. Relative frequencies can be specified with "frq" or counts with "cnts"
freqsize	frequency label cex value
legsymsize	legend symbol cex value
leglabsize	legend text cex value
legtxtlas	legend text position rotation passed to las. Numeric in 0,1,2,3; the style of axis label.

Details

Radial segment diagrams provide a compact way to illustrate profiles derived from SOM. Here diagrams are presented along the SOM grid in order provide a compact visualization of SOM results.s the map.

Value

a kohenen map where radial segment diagrams are used to illustrate profiles for each map node
