boxmap: Box plot of map and non-map data

Description

The boxmap function plots an attribute of a map and non-map data.

Usage

boxmap(source,layer='',attribute,type='',label="",col='',factor='')
"boxmap"(source,layer='',attribute,type='',label="",col='',factor='')
"print"(x,...)
"summary"(object,...)
"plot"(x,...)

Arguments

source

Folder path of the layer or map. Please quote the full folder path with forward slash "/". You can use R object as a source but you must set the layer parameter to "nofile"; see below

layer

The layer map in the folder that you want to work with. It is the full file name of map. This is case sensitive, please. In case you want to use non spatial data such as ".csv", ".txt", "dat" or ".tab" insert the full file name as layer. In case of using R object as a source set "layer" parameter to "nofile"

type

The type of box chart you want to plot. It can take "simple", "notch" Set the "type" to "map" if you want a map to be drawn for the attribute

attribute

The attribute name of the layer or the map you want use. In case you of using non spatial data such as ".csv", ".txt", "dat" or ".tab" attributes are variables or column names

factor

...

any other R parameters can be added
