Missing plotting symbol for geom_point when using shape
ggplot2, r
Solution
That's because `scales::shape_pal` defines a maximum of 6 values; try adding `scale_shape_manual(values=1:7)`
Problem
I must be obviously missing something simple, or this is a small bug. The geom_point () is always missing a plotting symbol when the shape=factor is used. This does not happen when color=factor is used. Appreciate your help. Here is a test code. ``` test <- data.frame(let=sample(LETTERS,7), id=c(1:7), y=c(id*7)) ggplot(data=test, aes(x=id, y=y))+ geom_point(aes(shape=let), size=6) ``` "Notice here the missing point (only 6 out 7) as one of the symbol is missing, which usually is alphabetically the last factor" ``` ggplot(data=test, aes(x=id, y=y))+ geom_point(aes(color=let), size=6) ``` "Here we see 7 points with different colors" Thanks, VJ
