Error in coord_proj()
I have used coord_proj() without an issue until today when I found that I get the following error.
Error in zero_range(from) : x must be length 1 or 2
It seems to occur with the example code provided with ggalt()
world <- map_data("world")
world <- world[world$region != "Antarctica",]
gg <- ggplot()
gg <- gg + geom_cartogram(data=world, map=world,
+ aes(x=long, y=lat, map_id=region))
gg <- gg + coord_proj("+proj=wintri")
gg
Error in zero_range(from) : x must be length 1 or 2
Any thoughts on why this error might occur? Thanks
It runs fine for me without the errant +
Travis CI wld be screaming at me if this particular example (without said syntax error) did not work :-)
Sorry that was pasting issue. I have reinstalled ggalt, ggplot2, both from CRAN and still get the same error. The code works until the coord_proj
line and then fails with the Error in zero_range(from) : x must be length 1 or 2
error.
can you post your output of sessionInfo()
or devtools::session_info()
?
I'm now pretty sure this is due to me compensating for some ggplot2 things by developing with ggplot2_2.2.1.9000 (i.e. github install).
Sorry for being so late getting back to this and I see this is likely a bug. I have tried reinstalling ggplot2 and any number of other packages and this still seems to be an issue. Here is my current session info, while trying to generate a new map.
Thanks for working on this. I really find the package useful.

yep. and i'm not sure how to easily handle the prod ggplot2 compat with dev ggplot2 compat.
short-term fix is to install dev ggplot2
So I've installed dev ggplot2 this way:
library(devtools) dev_mode(on = T) install.packages("ggplot2")
And still get the error. Am I doing something wrong?
Oops figured it out.
install_github("hadley/ggplot2")
But I think the dash (hyphen) in my name is creating problems with installing the dev package. Argh!
Now I do
withr::with_libpaths( new = "C:/Rdevlibs", install_github('tidyverse/ggplot2' ,force = T))
Which worked for the problem at hand with the code above! But I was trying primarily to get coord_proj to work with ggmap. Now I can't even get ggmap to work. I get:
worldmap<-get_map(location = c(lon = 0, lat = 0), scale=2,zoom=1, maptype = "terrain", source = "google") Source : https://maps.googleapis.com/maps/api/staticmap?center=0,0&zoom=1&size=640x640&scale=2&maptype=terrain&language=en-EN worldmap 1280x1280 terrain map image from Google Maps. see ?ggmap to plot it. p <- ggmap(worldmap) Error in get("f", environment(CoordMap$train)) : object 'f' not found
I am having the same issue as zoanthal. When I use cran versions of ggplot2, ggmap, and ggalt, I get the "Error in zero_range(from) : x must be length 1 or 2" from ggalt. When I use latest github versions of ggplot2, ggalt and ggmap, I get "Error in get("f", environment(CoordMap$train)) : object 'f' not found" from ggmap (commented out the coord_proj piece). This happens with the ggalt example code and with my CA State Plane II NAD83 US Feet PROJ4 definition.
Just a comment to say that I am also affected by the Error in zero_range(from) : x must be length 1 or 2
bug when runnning the CRAN version of ggplot
and ggalt
.
Errata: it happens not only with CRAN versions of ggplot
and ggalt
, but also with github versions!
I've been looking at this too. The problem seems to have been introduced in 02590ea. Presumably these are the changes that are meant to provide compatibility with the dev version of ggplot2. I reverted that commit in my copy, and coord_proj
seems to be working again with ggplot2 v. 2.2.1. Anyone who wants to try that version can grab the ggp221
branch of my fork.
For what it's worth, on the question of how to handle the case where the CRAN release of a package dependency has a different interface from the dev version, my advice would be to have your master branch compatible with the CRAN release, and have a separate branch with the changes needed for compatibility with the dev version. Then both versions are available to your users, with the default version of your package matching the default version of the dependency. Then, when they release the new version of the dependency, you can merge your compatibility patch into your main branch, and you'll be ready to go.
@rplzzz your branch's ggalt
doesn't seem to have geom_cartogram
, so I couldn't test whether it works or not.
EDIT: Also, trying to use geom_map
instead gives the following error:
Error in gPathFromVector(names) :
a 'grob' path must contain at least one 'grob' name
@aldomann I'm guessing you got the wrong branch, as geom_cartogram
is definitely there, in the file "geom_cartogram.r", but it's not there in the (old, outdated) master branch. Make sure to include the ref='ggp221'
argument to the install_github
statement.
You're right, I was using branch = "ggp221"
instead of ref = "ggp221"
. Must've misread the documentation. It totally works as expected.
Working with the latest CRAN versions of everything (was hoping it would be enough for the ggplot2
part) I get
