Point and Click Interface for Displaying Spatial Data

Plot spatial data with interactive (point-and-click) control over the plot.

Keywords
hplot, spatial
Usage
iplot(x, ...)

## S3 method for class 'ppp': iplot(x, ..., xname)

## S3 method for class 'layered': iplot(x, ..., xname)

## S3 method for class 'default': iplot(x, ..., xname)

Arguments
x
The spatial object to be plotted. An object of class "ppp", "psp", "im", "owin", or "layered".
...
Ignored.
xname
Optional. Character string to use as the title of the dataset.
Details

The function iplot generates a plot of the spatial dataset x and allows interactive control over the appearance of the plot using a point-and-click interface.

The function iplot is generic, with methods for for point patterns (iplot.ppp), layered objects (iplot.layered) and a default method. The default method will handle objects of class "psp", "im" and "owin" at least.

A new popup window is launched. The spatial dataset x is displayed in the middle of the window using the appropriate plot method.

The left side of the window contains buttons and sliders allowing the user to change the plot parameters.

The right side of the window contains navigation controls for zooming (changing magnification), panning (shifting the field of view relative to the data), redrawing and exiting.

If the user clicks in the area where the point pattern is displayed, the field of view will be re-centred at the point that was clicked.
