Thanks for providing some code that illustrates the problem — it's a great start 😄 However, your code is currently a bit too complicated: there's quite a bit of extraneous stuff in there that doesn't seem directly related to the problem. Can you please try and simplify your example some more? The more minimal you can make the reprex, the faster I can identify the problem and fix it.

[hadley]

Much better, thanks! Do you see the problem with other model types, or is it just xgbTree?

[cgoo4]

I was using gather_predictions on ranger and xgbTree, and encountered the problem after updating modelr. add_predictions used with each independently gives the same error.

Details

If I add `type = "raw"`, it runs per below. But the default (`type = NULL`) sufficed in v0.1.2.

library(caret) 
#> Loading required package: lattice
#> Loading required package: ggplot2
library(modelr)

mod <- train( 
  mpg ~ ., 
  data = mtcars, 
  method = "ranger"
) 

mod2 <- train( 
  mpg ~ ., 
  data = mtcars, 
  method = "xgbTree"
) 

gather_predictions(mtcars, mod, mod2, type = "raw")
