yoverx: Height / width ratio

In townleym/mSpatial: Some Convenience Functions building on the rGeos library

Description

Quick function for getting the 1/aspect ratio of a geometry

Usage

yoverx(geom, osm = T)

Arguments

geom	an sp geometry object Since map objects have varying aspect ratios, saving them to files results in lots of whitespace. This function enables you to specify the output dimensions in the same ratio as the sp object.

Examples

x = 800 # width in pixels
y = yoverx(basemap)
png(filename, width = x, height = y)
