Animate BirdFlow Migration Traffic Rate (BMTR)

Animate migration traffic rates produced by calc_bmtr().

Usage

animate_bmtr(bmtr, bf, title = species(bf), ...)

bmtr

A data frame created by calc_bmtr(format = "dataframe")

bf

A BirdFlow object

title

The plot title

Arguments passed on to plot_bmtr

subset: A subset of the transitions in bmrt to plot, can be a logical vector of the same length as the number of transitions in bmtr; a numeric index of transitions in bmtr, or a subset of the transition names in bmtr.
limits: Two numbers representing the range in bmtr values to display. Values outside of this range will be truncated to the range. With the default of NULL the entire range is plotted.
dynamic_scale: If TRUE then the range of the data in each transition is mapped to the color palette. This makes it easier to see the variation within a single transition but results in an inconsistent scale among transitions.
coast_linewidth: The line width used to plot the coast. Set to NULL to skip plotting the coastline.
coast_color: The color used to plot the coastline, or NULL to skip plotting the coastline.
gradient_colors: The colors palette used to represent the BMTR intensity.
value_label: The label for the BMTR values.
transform: A transformation to apply to the color scaling. "identity", and "sqrt" are recommended. If "log" is used zeros will be replaced with 1/2 the smallest non-zero value prior to transforming. Legend will still reflect the original values. Passed to ggplot2::scale_color_gradient().
