R ggmap Error: object 'f' not found

After I install rnoaa packages, my ggmap package is not working. I couldn't even do the simple example:

>library(ggmap)

>qmap(location = "boston university")

Error in get("f", environment(CoordMap$train)) : object 'f' not found

Does anyone have the same problem? Thank you!

@bethanyP I did reproduce the error with those 2 lines of code, although I'm unclear as to why it's happening. Even the following example from the ggmap help page for the get_map function doesn't work: map <- get_map(location = "texas", zoom = 6, source = "stamen"). ggmap(map, fullpage = TRUE) – Gibeonite 27/1, 2017 at 6:16

Code works fine for me. Close R, reopen and try again. Then load extra libraries one by one and test after each – Fiann 27/1, 2017 at 6:50

This is just a simple example that you don't need any data. @bethanyP – Hausmann 27/1, 2017 at 16:22

I even reinstall R, R studio and all packages, it still shows the error. @RichardTelford – Hausmann 27/1, 2017 at 16:26

Reverting to ggplot v. 2.2.0 worked for me: devtools::install_github("hadley/[email protected]")

Reinstall R and R Studio
Library(devtools) devtools::install_github("dkahle/ggmap") devtools::install_github("hadley/ggplot2")

Had the same error, and works fine now.

This is the best answer for most cases. Dont' revert to older versions, just update both ggmap and ggplot to their newest releases on github – Subteen 16/2, 2018 at 17:38

I had this problem as well, uninstalling ggplot2 and reinstalling it from CRAN worked for me.

My colleague fix this problem by installing the old version of ggmap. ggmap updated on 2016-01-23. The old version from 2015-12-19 works fine. For those who have the same problem, go to link below and download the old version of ggmap. It should fix the problem.

https://cran.r-project.org/web/packages/ggmap/index.html

I also had the problem with ggmap not working. Using the CRAN package "version", I saw that my installed version was 2.6.1, claimed by CRAN to be the latest version. But on GitHub I discovered version 2.7, downloaded it with devtools, and now my code is working.
