Unused argument error with ggplot position_dodge(preserve = "single")

I am getting error when trying to use the preserve argument to position_dodge() described here in the ggplot documentation. 

ggplot(
       mtcars,
       aes(
           factor(cyl),
           fill = factor(vs)
           )
        ) +
 geom_bar(position = position_dodge(preserve = "single"))

Error in position_dodge(preserve = "single") : unused argument (preserve = "single")

I am using R version 3.4.1 and ggplot2 version 2.2.1

Any suggestions? Thanks

It looks like the preserve argument is present in the development version of ggplot2 but for the moment only in the function position_dodge2() and not in the normal position_dodge() function. This link shows how I found that information: https://github.com/tidyverse/ggplot2/search?utf8=%E2%9C%93&q=preserve&type=

It's unclear to me why the online documentation (http://ggplot2.tidyverse.org/reference/index.html) shows preserve as a current, usable feature.

If you really want to use this function you could try installing the development version. I have no idea if that would be a good idea or not!

install.packages("devtools")
library(devtools)
devtools::install_github("tidyverse/ggplot2")
