An object returned from kernel3d, the space-time kernel smoothing
function
map
If false, don't plot the map display.
addimg
If true, overwrite successive images in the image display, else
make a fresh image plot each time.
ncol
Number of columns and rows for multiple images and maps.
Details
This function displays three linked views of the data. In the current
graphics window a temporal slice from the kernel smoothing is displayed.
Another graphics device is started to display a map of the data that
contributed to that time-slice. A third graphics device shows a
histogram of the times of the events. Clicking with the mouse
in this window with button 1 sets the time for the other
displays to the time on the x-axis of the histogram at the clicked point.
In this way the 3-dimensional kernel smoothed function can be browsed,
and the corresponding map of the data compared.
