tmap (version 1.6)

animation_tmap: Create animation

Description

Create a gif or mpeg animation from a tmap plot. The free tool ImageMagick is required.

Usage

animation_tmap(tm, filename = "animation.gif", width = NA, height = NA, delay = 40)

Arguments

tm

tmap object. In order to create a series of tmap plots, which will be the frames of the animation, it is important to set nrow and ncol in tm_facets, for otherwise a small multiples plot is generated. Commonly, where one map is shown at a time, both nrow and ncol are set to 1.

filename

filename of the video (should be a .gif or .mpg file)

width

width of the animation file (in pixels)

height

height of the animation file (in pixels)

delay

delay time between images (in 1/100th of a second)

Examples

## Not run: 
# data(World, metro, Europe)
# 
# m1 <- tm_shape(Europe) + 
# 	      tm_polygons("yellow") +
# 	  tm_facets(by = "name", nrow=1,ncol=1)
# 
# animation_tmap(m1, filename="European countries.gif", width=800, delay=40)
# 
# m2 <- tm_shape(World) +
#           tm_polygons() +
#       tm_shape(metro) + 
#           tm_bubbles(paste0("pop", seq(1970, 2030, by=10)), 
#               border.col = "black", border.alpha = .5) +
#       tm_facets(free.scales.symbol.size = FALSE, nrow=1,ncol=1) + 
#       tm_format_World(scale=.5)
# 
# animation_tmap(m2, filename="World population.gif", width=1200, delay=100)
