Code Through Question

[sjone128]

I'm having a problem when I try to knit my code through document. I am using the starwars data set in the ggplot package. All of my chunks work but when I try to knit it together, this is the error.

Line 22 Error in ggplot(data = starwars) : object 'starwars' not found Calls: ... withCallingHandlers -> withVisible -> eval -> eval -> ggplot Execution halted

Here is the offending chunk. It is also the first time I call ggplot in the library or the starwars data set.

library(ggplot2)
ggplot(data = starwars) + 
   geom_bar(mapping = aes(x = eye_color))

The chunk runs fine, I'm not sure what I'm missing.

thanks!

Cool! If you type help(starwars) or ?starwars, you'll see in the first lines of the built-in documentation that starwars is from package dplyr - so try library(dplyr) in the beginning of your script.

See if that knits and let us know!
