zo: Zooms out on current plot

In jhollist/quickmapr: Quickly Map and Explore Spatial Data

Zooms out on current plot

Description

Interactively zoom out on the current plot. Works on an existing qmap object. Simply pass that object to zo(). A single zoom out results and the extent of the qmap object is changed.

Usage

zo(qmap_obj = NULL, zoom_perc = 0.5, loc = NULL)

Arguments

qmap_obj	A qmap object. Optional, but performs better with larger data sets.
zoom_perc	A proportion to determine the zoom level. The x and y axes are increased by this amount. Default is 0.5.
loc	A list with an x and y numeric indicating a location. Default is to interactively get loc value until escaped.

Examples

## Not run: 
data(lake)
qm<-qmap(list(lake,buffer,elev))
zo(qm)

## End(Not run)
