Error : `Error in find_subclass("Geom", geom, parent.frame()) : could not find function "find_subclass"`

[sebastiansauer]

Running the following function:

`gf_point(hp ~ mpg, data = mtcars)``

I got this error:

Error in find_subclass("Geom", geom, parent.frame()) : 
  could not find function "find_subclass"

I assume there are some issues with updates related to R 3.5.0 (?)

What I tried:

• I reinstalled mosaic and ggplot2
• I closed and restarted R
• I installed the github (but not the beta) versions for mosaic and ggplot2

Seems to be a problem with ggplot2_2.2.1.9000: It worked fine with me for ggplot2_2.2.1(CRAN) but with ggplot2_2.2.1.9000 (github) I get the same error.

If you use Github release of ggplot2, you also need the ggplot2.3 branch of ggformula.

[rpruim]

You can install the required version (for now) with

devtools::install_github("ProjectMOSAIC/ggformula", ref = "ggplot2.3")

[sebastiansauer]

Thanks, worked out.

@rpruim Will the ggplot2.3 branch be on CRAN by fall? Just hoping to switch everything to ggformula this fall. Thanks!

[rpruim]

It's already there. I expect another update in the next 1-2 weeks that will required the new version of ggplot2 (we couldn't do that until it was on CRAN). That will avoid the hassle of having to update ggformula after updating ggplot2 (and offer a few other improvements).

But as long as you update ggplot2 first and ggformula after, you should be good to go using the CRAN versions already now.

It would be great if the new versions of ggplot2 and mosaic could get on CRAN prior to the JSM, as I'm planning some outreach during the pre-JSM workshops and during the conference.
