The map function plots an attribute of a map. It can plot lines, polygons and points.
Usage
map(source,layer='',attribute,type='',label="",col='',symbol='')
## Default S3 method:
map(source,layer='',attribute,type='',label="",col='',symbol='')
## S3 method for class 'map'
print(x,...)
## S3 method for class 'map'
summary(object,...)
## S3 method for class 'map'
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 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 ogram chart you want to plot. Set the "type" to "points" if you want a map to be drawn for the point attribute
attribute

label
The labeling title of the chart. The title or topic of the graph
col

Incase of plotting a point data, you can set it to any symbol from your key board. For example you may use "H" to represent hospitals or set it to "P" to represent plants
x

object
an object of class "map", i.e., a fitted model.
...
any other R parameters can be added
Value
Objects of the class that basically list its elements
data
Original data for the model
table
