Re: ggplot Multiple Regression Lines

[Hadley Wickham]

You've given each woman a unique identifier so there is only one data
point per person. It's hard to fit a line to one point ;)

I am guessing you have too many "group"s. "id" should be a meaningful factor with which one can perform a regression. This example is not reproducible so I/we can't help you much further (if I have helped you at all).
