Draws (in a 2 by 2 layout) the following plots: a scatter plot with a color scale, the scatter plots of the response against the (first two) coordinates and the histogram of the response values.

```
scattersplot(x, ...)
# S3 method for default
scattersplot(
x,
z,
main,
xlab,
ylab,
zlab,
col = hot.colors(128),
lowess = TRUE,
density = FALSE,
omd = c(0.05, 0.95, 0.01, 0.95),
...
)
# S3 method for SpatialPointsDataFrame
scattersplot(
x,
data.ind = 1,
main,
xlab,
ylab,
zlab,
col = hot.colors(128),
lowess = TRUE,
density = FALSE,
omd = c(0.05, 0.95, 0.01, 0.95),
...
)
```

- x
object used to select a method.

- ...
additional graphical parameters (to be passed to

`spoints`

).- z
vector of data (response variable).

- main
an overall title for the plot.

- xlab
a title for the axis corresponding to the first coordinate.

- ylab
a title for the axis corresponding to the second coordinate.

- zlab
a title for the axis corresponding to the response.

- col
color table used to set up the color scale (see

`spoints`

).- lowess
logical. If

`TRUE`

, a`lowess`

smooth is added to the plots of the response against the coordinates.- density
logical. If

`TRUE`

, a kernel`density`

estimate is added to the histogram.- omd
a vector of the form

`c(x1, x2, y1, y2)`

giving the region inside outer margins in normalized device coordinates (i.e. fractions of the device region).- data.ind
integer (or character) with the index (or name) of the data component.

No return value, called for side effects (generate the plot).

Standard generic function with a default method, in which argument `x`

is a matrix with the spatial coordinates (each row is a point).

`scattersplot.SpatialPointsDataFrame`

sets default values for some of the arguments
from attributes of the object `x`

(if present; see e.g. `precipitation`

).
