ggmap error (Error in as.vector(y) : attempt to apply non-function)

Question

I'm doing relatively simple things with ggmap and am confused because code that runs fine on my mac does not run on my PC.

I run this code:

library(ggmap)

map <- get_map(location = c(-122.175, 37.45635),
               maptype = "terrain",
               source = "google",
               crop = FALSE,
               zoom = 7)
 ggmap(map)

, which runs fine on my mac, but throws this error on my PC:

Error in as.vector(y) : attempt to apply non-function

Any help would be much appreciated.

Unable to reproduce, works fine on my Windows machine. Try restarting R, or reinstalling the package. – Houck

Right, it works fine on my mac as well + I of course already tried restarting R and restarting my computer. That's why I posted the question - to see if anyone might have any ideas on what could be going wrong on a PC. Thanks though. – Tunis

Answer 1

It is no longer necessary to uninstall ggplot2 to fix this error. I was able to update ggplot by running install.packages("ggplot2"), then reinstall ggmap. This solved the problem for me.

I confirm that updating from ggplot2 2.1.0 to ggplot2 2.2.1 also worked for me. – Rutheruthenia

Answer 2

I faced that problem after installing R and RStudio last week. Restarting RStudio or R session, or reinstalling ggmap package didn't work for me. I'd just fixed it with these steps:

• Uninstall R and RStudio
• Delete old folders related to R and RStudio in Program Files (I had things like older versions of R).
• Delete Windows temporary files (just in case)
• Install R and RStudio again
• Install ggmap package

Thank you! This is what ended up working on my work PC. Whew :) – Tunis

Answer 3

I guess this problem comes from the last update of ggplot2. See the following links:

• https://github.com/tidyverse/ggplot2/blob/master/NEWS.md#extensions
• ggmap Error: GeomRasterAnn was built with an incompatible version of ggproto

You could try to install an older version of ggplot (see below) or try to reinstall the packages like suggested in the link above.

    library(devtools)
    install_version("ggplot2", version = "2.1.0", repos = "http://cran.us.r-project.org")

Yes, I ended up then having this same trouble on my mac and this solution also worked for me -- thank you! (But also a bummer that I can't also utilize the new ggplot2 features - oh welll - this is what iterations are for I suppose!) – Tunis

My experience seems to be the opposite (in Windows with RStudio): I had this error with ggplot2 2.1.0 and solved it by upgrading to ggplot2 2.2.1. – Rutheruthenia

Answer 4

You don't need to Unistall R. Just erase ALL folders related to ggplot2, and reinstall the ggmap with all dependencies.
