How to add color aesthetic to geom_line stat layer

[Art]

Hello all,

I'm trying to plot the mean for each group using the same colors as the points.

This is my plot code.

How do I change geom_line so that the lines are the same as the group colors?

test <- ggplot(aes(x = x, y = y, group = group), data = data) +

  geom_point(aes(colour = group)) +

  geom_line(stat = 'summary', fun.y = mean)

Thanks!

Sorry, I figured it out.

test <- ggplot(aes(x = x, y = y, group = group), data = data) +

  geom_point(aes(colour = group)) +

  geom_line(stat = 'summary', fun.y = mean, aes(colour = group)

Try

test <- ggplot(aes(x = x, y = y, group = group, colour = group), data = data) +
geom_point() +

geom_line(stat = 'summary', fun.y = mean)

Aesthetics defined in the ggplot() statement apply to all layers.
Defining aesthetics inside a geom() call make them local to the layer
in which they are defined.
