Multiple ggplots with magrittr tee operator

Question

I am trying to figure out why the tee operator, %T>%, does not work when I pass the data to a ggplot command.

This works fine

library(ggplot2)
library(dp         


        

Answer 1

I think your problem has to do with order of operations. The + is stronger than the %T>% operator (according to the ?Syntax help page). You need to pass in the data= parameter to ggplot before you add the geom_point otherwise things get messy. I think you want

mtcars %T>%
  {print(ggplot(.) + geom_point(aes(cyl, mpg)))} %>%
  {ggplot(.) + geom_point(aes(mpg, cyl))}

which uses the functional "short-hand" notation
