How could I suppress the rendering progress message?

[zhengchencai]

Hi there,

May I ask if there is a way to suppress the rendering progress message? It is very helpful in most cases but it's not necessary to print them in HTML output from knitr. It seems I need to hack this line https://github.com/thomasp85/gganimate/blob/299fd586ce6c0ec2571dc0a07c8986c1317292f9/R/renderers.R#L114 but I wonder if there is an argument when using animate() function. Thank you very much.
