In Envirometrix/plotKML: Visualization of Spatial and Spatio-Temporal Objects in Google Earth

Generates a legend bar (PNG file)

Description

Produces a PNG file that can be used as a screen overlay — legend bar for numeric and factor type variables.

Usage

kml_legend.bar(x, width, height, pointsize = 14, legend.file, legend.pal, 
     z.lim = range(x, na.rm=TRUE, finite=TRUE), factor.labels, png.type)

Arguments

x	numeric or factor-type vector
width	numeric; (optional) width of image in pixels
height	numeric; (optional) height of image in pixels
pointsize	numeric; point size for the plot
legend.file	PNG file name
legend.pal	character; color palette
z.lim	numeric; lower and upper limits
factor.labels	character; class names if applicable
png.type	character; PNG type

Details

When exporting raster layers to KML the legend bar is generated by default. If the width and height are not provided, the function will try to estimate them automatically.
