The following code works fine:
library(ggfortify)
autoplot(lm(Petal.Width ~ Petal.Length, data = iris), label.size = 3)
However ggfortify::autoplot and ggfortify:::autoplot do not work as expected. See below the codes with errors:
ggfortify::autoplot(lm(Petal.Width ~ Petal.Length, data = iris), label.size = 3)
Error: 'autoplot' is not an exported object from 'namespace:ggfortify'
ggfortify:::autoplot(lm(Petal.Width ~ Petal.Length, data = iris), label.size = 3)
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
object 'autoplot' not found
Wonder what I am missing here. Thanks in advance for any help.

As @hrbrmstr indicates in his comment the correct way to call autoplot is:
library(ggfortify)
ggplot2::autoplot(lm(Petal.Width ~ Petal.Length, data = iris), label.size = 3)
autoplot() is a function of ggplot that calls UseMethod("autoplot").
