Setting Defaults for geoms and scales ggplot2

Question

Theming for ggplot2 makes it quite easy to relegate the need for multiple or repetitive + opt()... lines. However, I would like to know if there is a way to def

Answer 1

I can't think of anything useful for the geoms, but for the scales, one option would be to use the fact that components of ggplots are all simply R objects that can be saved, stored and reassigned like any other.

So you could perhaps create your own collection of "default" versions of many scales, like:

sfmDefault <- scale_fill_manual(...)
scmDefault <- scale_colour_manual(...)

etc. with your desired default values. Put them in your .RProfile or wherever and use them as needed.
