Required packages are not loaded

Hello!

IntegratedLearner depends on several packages, for instance tidyverse:

IntegratedLearner/DESCRIPTION

Line 18 in b56f9c7

tidyverse

However, the functions are not listed in NAMESPACE:

https://github.com/himelmallick/IntegratedLearner/blob/master/NAMESPACE

... and they are used without package specification:

IntegratedLearner/R/plotLearner.R

Line 15 in b56f9c7

clean_base_learner <- str_remove_all(fit$base_learner, 'SL.')

This means that these functions are not loaded when IntegratedLearner is loaded. This leads to errors where certain function is not found.

Error in str_remove_all(fit$base_learner, "SL.") : 
  could not find function "str_remove_all"

The problem is rather frustrating for user to solve.
