sommix_bar: Plots SOM profiles using bar charts

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

Description

Barplots are used to represent standardized summary values of components under each SOM profile using bars of various lengths.

Usage

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

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.
barstat	specifies summary statistic to plot as bars. "MED" and "AVG" are available

Details

Barplots are a straighforward way to show patterns in component values under each SOM profile. The size of the bar represents the component summary under each profile. Error bars are also provided. between obser

Value

a kohonen plot that uses barplots to describe the profiles for each map node.
