Methods for 'myGrid' Objects.

Description

Methods for the result of initGrid (myGrid object)

Usage

## S3 method for class 'myGrid'
print(x, ...)

## S3 method for class 'myGrid'
summary(object, ...)

## S3 method for class 'myGrid'
plot(x, show.names = TRUE, names = 1:prod(x$dim), ...)

Arguments

x	myGrid object
...	Further arguments to the plot function.
object	myGrid object
show.names	Whether the cluster names must be printed in center of the grid or not. Default to TRUE (names not displayed).
names	If show.names = TRUE, values of the names to display. Default to the cluster number.

Details

The myGrid class has the following entries:

• coord 2-column matrix with x and y coordinates of the grid units

• topo topology of the grid;

• dim dimensions of the grid (width corresponds to x coordinates)

• dist.type distance type that defines the topology of the grid.

During plotting, the color filling process uses the coordinates of the object x included in x$coord.

Examples

# creating grid
a.grid <- initGrid(dimension=c(5,5), topo="square", dist.type="maximum")

# plotting grid
# without any color specification
plot(a.grid)
# generating colors from rainbow() function
my.colors <- grDevices::rainbow(5*5)
plot(a.grid) + ggplot2::scale_fill_manual(values = my.colors)
