map.path: Map path along an ordered variable

In Rsoc/soc.ca: Specific Correspondence Analysis for the Social Sciences

Map path along an ordered variable

Description

Plot a path along an ordered variable. If the variable is numerical it is cut into groups by the min_cut function.

Usage

map.path(
  object,
  x,
  map = map.ind(object, dim),
  dim = c(1, 2),
  label = TRUE,
  min.size = length(x)/10,
  ...
)

Arguments

object	is a soc.ca result object
x	is an ordered vector, either numerical or factor
map	is a plot object created with one of the mapping functions in the soc.ca package
dim	the dimensions in the order they are to be plotted. The first number defines the horizontal axis and the second number defines the vertical axis.
label	if TRUE the label of the points are shown
min.size	is the minimum size given to the groups of a numerical variable, see min_cut.
...	further arguments are passed onto geom_path, geom_point and geom_text from the ggplot2 package

Examples

example(soc.ca)
map <- map.ind(result, point.color = as.numeric(sup$Age))
map <- map + scale_color_continuous(high = "red", low = "yellow")
map.path(result, sup$Age, map)
