mapChoroTypo: Typology

In rCarto: This package builds maps with a full cartographic layout.

Description

This function represents a qualitative variable through a map. Polygons are filled in relation to the variable modalities.

Usage

mapChoroTypo(shpFile, shpId, df, dfId, var, 
             posLeg = "bottomleft", palCol = "Paired", NACol = "grey", 
             title = var, legend = var, author = "author", sources = "sources", 
             scalebar = FALSE, scalebarSize, scalebarText, 
             northArrow = FALSE, northArrowSize, 
             width = NULL, height = NULL, txtCex = NULL)

Arguments

shpFile	Path to a polygon shapefile.
shpId	Unique identifier of the shapefile. It must correspond to dfId.
df	Data frame that contains the variable to be mapped.
dfId	Unique identifier of the data frame. It must correspond to shpId.
var	Name of the qualitative variable to be mapped.
posLeg	Position of the legend (top, bottom, left, right, center, topleft, topright, bottomleft or bottomright).
palCol	Color palette, provided through RColorBrewer, to be used in the map. Use display.brewer.all() to see the available color ramps. For a more detailed overview : RColorBrewer.
NACol	Color used to draw units with no data (NA).
title	Title of the map.
legend	Title of the legend.
author	Two lines (author and sources) at the bottom of the map are available to display additional information. It is recommended to display the name of the author and the sources of the data and the base map.
sources	Two lines (author and sources) at the bottom of the map are available to display additional information. It is recommended to display the name of the author and the sources of the data and the base map.
scalebar	FALSE (default): don't draw a scale bar. TRUE : draws a scale bar. The choice of the scale bar location is interactive.
scalebarSize	Size of the scale bar in map units.
scalebarText	Text of the scale bar.
northArrow	FALSE (default) : don't draw a North arrow. TRUE : draws a North arrow. The choice of the North arrow location is interactive.
northArrowSize	Size of the North arrow in map units.
width	Width of the map in cm.
height	Height of the map in cm.
txtCex	Size of the texts.

Details

Only the five first arguments are compulsory.

Value

A typology map is displayed in the graphic window.
You can export the map in raster or vector format (pdf).
