plot_fire_mov: Plotting the fire movement

Description

This function plots the fire movement. The fire movement is calculated from get_fire_mov().

Usage

plot_fire_mov(
  result,
  cluster = "all",
  hotspot = TRUE,
  from = NULL,
  to = NULL,
  step = 1,
  bg = NULL
)

Value

A ggplot object. The plot of the fire movements.

Arguments

result

spotoroo object. A result of a call to hotspot_cluster().

cluster

Character/Integer. If "all", plot all clusters. If an integer vector is given, plot corresponding clusters.

hotspot

Logical. If TRUE, plot the hot spots.

from

OPTIONAL. Date/Datetime/Numeric. Start time. The data type needs to be the same as the provided observed time.

to

OPTIONAL. Date/Datetime/Numeric. End time. The data type needs to be the same as the provided observed time.

step

Integer (>0). Step size used in the calculation of the fire movement.

bg

OPTIONAL. ggplot object. If specified, plot onto this object.

  # Plot cluster 1 to 4

  # Plot cluster 1 to 4, set step = 6
