plot_distr {ElevDistr}

Plot the sampled area

Description

With this function it is possible to plot the analyzed area. However you need to register a APIs. If you are not willing to do this, you cannot plot and the function will throw a warning. See: https://www.rdocumentation.org/packages/ggmap/versions/3.0.0.

Usage

plot_distr(nearestCorner, grid, treelineDf, size = 12)

Arguments

nearestCorner

A list containing the longitude and the latitude (WGS 84) of the point which is used to load the map. The values must be of the data type "numeric" and finite.

grid

Data frame generated by the function classify_above_treeline and therefore containing: longitude, latitude (WGS 84), growing season temperature, growing season length, and a boolean. Longitude and latitude must be of the data type "numeric" and finite. For the boolean TRUE, FALSE and NA is allowed and nothing else.

treelineDf

A data frame containing line-shaped polygons. Each row containing: a identifier, a start latitude and longitude, a end latitude and longitude (all WGS 84). All longitude and latitude parameters must be of the type "numeric" and finite.

size

Map zoom, for the "get_map" function of the "ggmap" library. One value, data type "integer", finite and in the range from 3 to 21.

Value

Nothing.
