.... hi got issues running ggplot2, i'm trying through basic online tutorial issue, trying run qplot in 1 of exercises got errors listed above, i've read around bit on previous lookups, went through motions of:

  • install.packages("proto")
  • install.packages('ggplot2', dep = true),
  • rebooting r - still getting error. other "answer"?

@mlavoie, mike wise

i had same error after installing ggplot2. 2 ways around this:

1) need load "library(ggplot2)" before call qplot()

library(ggplot2) qplot(factor(class), volume, data = abalone, geom = "boxplot")

2) discovered randomly adding "ggplot2::" in front of code makes work, without calling library.

ggplot2::qplot(factor(class), volume, data = abalone, geom = "boxplot")
