Build fail on local #104

Closed SteveBronder closed 7 years ago

SteveBronder commented 7 years ago

I'm trying to do ./build on the current docs and am getting the error

Knitting file 'bagging.Rmd' ...
Quitting from lines 64-71 () 
Error in train.default(learner = bag.lrn, task = bh.task, subset = train.inds) : 
  argument "y" is missing, with no default
Calls: lapply ... withVisible -> eval -> eval -> train -> train.default
Execution halted

Odd, I think it is trying to run carets train function?

SteveBronder commented 7 years ago

Looking at ./build this appears to have been an issue before. On line 111

  library(caret) # we get problems if this shadows "mlr::train"
SteveBronder commented 7 years ago

Resolved in the short term

If you have mlr loading automatically in your Rprofile then it will load before caret is loaded, causing caret's train to be called first

Is there a way in build to set the --vanilla option for Rscript?

yes, thats correct. i am not sure what to do against this except for removing mlr from your Rprofile. i usually just load very smallish helper packages in my Rprofile.
