From sp v1.4-4
by Edzer Pebesma

##### Class "GridTopology"

class for defining a rectangular grid of arbitrary dimension

- Keywords
- classes

##### Objects from the Class

Objects are created by using e.g.

GridTopology(c(0,0), c(1,1), c(5,5))

see SpatialGrid

##### Slots

`cellcentre.offset`

:numeric; vector with the smallest centroid coordinates for each dimension; coordinates refer to the cell centre

`cellsize`

:numeric; vector with the cell size in each dimension

`cells.dim`

:integer; vector with number of cells in each dimension

##### Methods

- coordinates
`signature(x = "SpatialGrid")`

: calculates coordinates for each point on the grid- summary
`signature(object = "SpatialGrid")`

: summarize object- coerce
`signature(from = "GridTopology", to = "data.frame")`

: convert to data.frame with columns cellcentre.offset, cellsize and cells.dim

##### See Also

##### Examples

```
# NOT RUN {
x = GridTopology(c(0,0), c(1,1), c(5,5))
class(x)
x
summary(x)
coordinates(x)
y = SpatialGrid(grid = x)
class(y)
y
# }
```
