Hi R - listers, I am receiving an error. Does anyone know what this means? J
This command:
ggplot(subset(foo, Rayos != "Rayos.NA"), aes(x=HTL, y=DevelopIndex, colour=TotalEggs)) +geom_point() +geom_jitter() + facet_grid(Aeventexhumed ~ Rayos)
... ends here. This command:
+ geom_smooth(method="lm", fill=NA) + ylim(c(0, 7))
makes no sense in isolation. Hence
Error in +geom_smooth(method = "lm", fill = NA) : invalid argument to unary operator
I suppose the + wants to be on the preceding line.
