Simplify a polygon shape by straightening out jittery lines

1	simplify(map, tol = 0.01)

`map`	map object as generated by functions such as 'process_shape', 'ggplot2::map_data', or 'ggplot2::fortify'
`tol`	tolerance to use for simplifying the map. Larger tolerances will lead to smaller maps at lower resolutions.

states05 <- simplify(states, 0.001)
states05 %>% ggplot(aes(x = long, y = lat)) + geom_path(aes(group = group))
states01 <- simplify(states, 0.01)
states01 %>% ggplot(aes(x = long, y = lat)) + geom_path(aes(group = group))
