plot_flowmap: Visualize flowmap.

In caesar0301/movr: Analyzing and Visualizing Human Mobility Data

Visualize flowmap.

Description

Visualize the mobility statistics (flowmap) from data. Each row in the data will generate a line on the map.

Usage

plot_flowmap(
  from_lat,
  from_lon,
  to_lat,
  to_lon,
  dist.log = TRUE,
  weight = NULL,
  weight.log = TRUE,
  gc.breaks = 5,
  col.pal = c("white", "blue", "black"),
  col.pal.bias = 0.3,
  col.pal.grad = 200,
  new.device = TRUE,
  bg = "black",
  ...
)

Arguments

from_lat	The latitude coordinates of departing point for mobile transitions.
from_lon	The longitude coordinates of departing point for mobile transitions.
to_lat	The latitude coordinates of arriving point for mobile transitions.
to_lon	The longitude coordinates of arriving point for mobile transitions.
dist.log	Whether using log-scale distance for line color.
weight	The user-defined weight for line color. Larger weight corresponds to lefter color of col.pal.
weight.log	Whether using log-scale weight for line color.
gc.breaks	The number of intermediate points (excluding two ends) to draw a great circle path.
col.pal	A color vector used by colorRampPalette; must be a valid argument to col2rgb. Refer to colorbrewer2.org to derive more palettes.
col.pal.bias	The bias coefficient used by colorRampPalette. Higher values give more widely spaced colors at the high end.
col.pal.grad	The number of color grades to differentiate distance.
new.device	Whether creating a new device for current plot. Set this parameter as FALSE when trying to plot multiple flowmaps in one figure.
bg	The background color for current plot. It is working when new.device is TRUE.
...	Extra parameters for basic plot() function.
