Add spatial representation of polygon layout to a ggplot2 object.

plot_add_polygon_overview(plot, bgm_as_df, polygon_overview = 0.2)

Arguments

plot	ggplot2 object. Can be a ggplot grob.
bgm_as_df	*.bgm file converted to a dataframe. Please use `convert_bgm` to convert your bgm-file to a dataframe with columns 'lat', 'long', 'inside_lat', 'inside_long' and 'polygon'.
polygon_overview	numeric value between 0 and 1 indicating the size used to plot the polygon overview in the upper right corner of the plot. Default is `0.2`.

Value

ggplot grob

Examples

d <- system.file("extdata", "setas-model-new-trunk", package = "atlantistools")
bgm_as_df <- convert_bgm(bgm = file.path(d, "VMPA_setas.bgm"))

p <- plot_line(preprocess$physics, wrap = NULL)
p <- custom_grid(p, grid_x = "polygon", grid_y = "variable")

grob <- plot_add_polygon_overview(p, bgm_as_df)
gridExtra::grid.arrange(grob)
