Does anyone of you know about BBS specific to ggplot2?
Thanks in advance for your kind reply.
I do not want to make "10 to digit " only once in an axis.
How to work around?

This question is ambiguous, please be more explicit.

This is a forum for discussing Stan, not general issues with ggplot2. They have their own list:

http://ggplot2.org

If it’s a Stan-related question, you’ll have to be more specific.
