Animate a plot along a continuous time

Source: R/animate.R
transition_time.Rd

transition_time() is like transition_states() but treats time as a continuous quantity: the states are its distinct values and each transition is allocated frames in proportion to its time gap, so the animation plays at a constant rate through unevenly spaced times. There is no pause on a state and no wrap — time flows once, start to finish.

Usage

transition_time(plot, time)

Arguments

plot

A PlotSpec (from vplot()).

time

A numeric column giving each row's time.

Value

The modified PlotSpec.
