I am plotting ggplot smooth line. I would like to add dots to the regression
line, the dots are shaped under different condition.
p <- ggplot(data, aes(x = x, y = y,
shape = assign, linetype = factor(sex)))
p0b <- p+
scale_linetype_manual(breaks=c("0","1"), values=c(1,2)) +
geom_smooth(aes(shape = assign, linetype = female), method = "lm", se =
FALSE, size = 1.2)
the dots on the smooth line should be shaped by assign. how can i do it?
maybe i should add something like
scale_shape_manual(values=c(17, 0, 19))
