In sageR: Applied Statistics for Economics and Management with R

Calcule les trajectoires par axe pour un diagramme en radar (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

Examples

library(dplyr)
library(scales)
library(tibble)

mtcars_radar <- mtcars %>%
  as_tibble(rownames = "group") %>%
  mutate_at(vars(-group), rescale) %>%
  tail(4) %>%
  select(1:10)
plot.data <- as.data.frame(mtcars_radar)
if(!is.factor(plot.data[, 1])) {
  plot.data[, 1] <- as.factor(as.character(plot.data[, 1]))
  }
names(plot.data)[1] <- "group"
var.names <- colnames(plot.data)[-1]
grid.min = 0
grid.max = 1
centre.y = grid.min - ((1 / 9) * (grid.max - grid.min))
CalculateAxisPath(var.names, grid.min + abs(centre.y), grid.max + abs(centre.y))
