zi: Zooms in on current plot

In jhollist/quickmapr: Quickly Map and Explore Spatial Data

Zooms in on current plot

Description

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

Usage

zi(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 reduced 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)
x<-qmap(list(lake,buffer,elev))
zi(x)

## End(Not run)
