Package 'ggradar'

Calculate Axis Path

Description

Calculates x-y coordinates for a set of radial axes (one per variable being plotted in radar plot)

Usage

CalculateAxisPath(var.names, min, max)

Arguments

var.names	list of variables to be plotted on radar plot
min	MININUM value required for the plotted axes (same value will be applied to all axes)
max	MAXIMUM value required for the plotted axes (same value will be applied to all axes)

Value

a dataframe of the calculated axis paths

Calculate Group Path

Description

Converts variable values into a set of radial x-y coordinates

Usage

CalculateGroupPath(df)

Arguments

df	a dataframe with Col 1 is group ('unique' cluster / group ID of entity) and Col 2-n are v1.value to vn.value - values (e.g. group/cluser mean or median) of variables v1 to v.n

Value

a dataframe of the calculated axis paths
