See vignette("timing") for more info; the x-axis of the diagrams are time.ram().
Arguments
- RAM
RAM object.
Details
= RAM$time - time.sec()
Examples
if (FALSE) { # \dontrun{
#the time.ram() at the end of each frame is stored in RAM$debug$ahead.
#Plotting it can help visualize how the RAM stays synced in time:
quickload(BadApple)
#^C after 10 seconds or so
plot(RAM$debug$ahead, type='l', xlab='Tick')
} # }
