Consistent as.character(formula)==3L error

[rjfhoffman]

Hello,

In the last week, missRanger has been giving an error that "length(formula <- as.character(formula)) == 3L is not TRUE". This error is also coming up when I ran the vignette code to see if it was an issue with my data, but this error comes up every time:

irisImputed <- missRanger(irisWithNA, pmm.k = 3, num.trees = 100, verbose = 0)
irisImputed <- missRanger(irisWithNA, formula= .~.-Species, pmm.k = 3, num.trees = 100, verbose = 0)

Thanks for reporting!

Hello @rjfhoffman : the error is likely to come from loading package "moderndive". It imports formula.tools:::as.character.formula(), which breaks base:::as.character().

In 2019(!) I opened this issue

decisionpatterns/formula.tools#11

without answer from the developers.

Can you check in a fresh session without loading any of the above packages?

After starting a fresh session without including these packages (or other packages that require them) missranger runs again

Perfect. The issue with above package is still unfortunate.
