Add ggplot2 insets to a map

Share:

Description

This is identical to ggplot2::annotation_custom for use with ggmap

Usage

1
inset(grob, xmin = -Inf, xmax = Inf, ymin = -Inf, ymax = Inf)

Arguments

grob

grob to display

xmin, xmax

x location (in data coordinates) giving horizontal location of raster

ymin, ymax

y location (in data coordinates) giving vertical location of raster

Details

Most useful for adding tables, inset plots, and other grid-based decorations

Note

annotation_custom expects the grob to fill the entire viewport defined by xmin, xmax, ymin, ymax. Grobs with a different (absolute) size will be center-justified in that region. Inf values can be used to fill the full plot panel
