Importing Error

[renanxcortes]

Hello,

I'm facing an issue using the library now that I didn't have before. I even updated to R 3.6.1, but this persisted:

> library(ggtern)
Error: package or namespace load failed for ‘ggtern’:
 .onLoad failed in loadNamespace() for 'ggtern', details:
  call: modify_list(vals, list(..., ... = NULL))
  error: could not find function "modify_list"

Any clue of how to overcome this?

Best,
Renan

I am getting the same error in a clean session. I upgraded from 3.6.0 to 3.6.1 because of the error and it also persisted here.

@renanxcortes; I got it to work by installing from source in a clean R session:

install.packages("ggtern", type = "source")
library("ggtern")
