Error in zero_range(from) : x must be length 1 or 2

[matteomanca]

Hi all,

I'm trying the following code:

library(ggmap) barcelona <- get_map(location = 'barcelona', zoom = 13) ggmap(barcelona)

but I get the following error:

"Error in zero_range(from) : x must be length 1 or 2"

Any suggestion? Thanks in advance.

The map plots fine for me. Does the error occur when running the final command, ggmap(barcelona)? Can you report the output of str(barcelona)? For example:

> str(barcelona)
 'ggmap' chr [1:1280, 1:1280] "#DAE7CF" "#DAE7CF" "#DAE7CF" "#E1E1DD" ...
 - attr(*, "bb")='data.frame':  1 obs. of  4 variables:
  ..$ ll.lat: num 41.3
  ..$ ll.lon: num 2.12
  ..$ ur.lat: num 41.4
  ..$ ur.lon: num 2.23
 - attr(*, "source")= chr "google"
 - attr(*, "maptype")= chr "terrain"
 - attr(*, "zoom")= num 13

Also, at least the versions of ggmap and ggplot2 are good to know for the sake of reproducibility:

> packageVersion("ggplot2")
[1] ‘2.2.0’
> packageVersion("ggmap")
[1] ‘2.6.1’

This seems to be a duplicate of issue #113 .

I solved by reinstalling "ggplot2" and "ggmap". Probably it was due to the version of ggmap.
Currently I'm using:

 packageVersion("ggplot2")
[1] ‘2.2.0’
> packageVersion("ggmap")
[1] ‘2.6.1’

Sorry to duplicate an existing issue.

Bests,

I'm not bothered by the duplication. I think it's difficult to find duplicates if the original issue report has a somewhat poorly chosen title. Good that it works for you now!
