Unlike other functions the source for randomForest() does’t come up when I write randomForest in R.
I’ve also tried some other commands like:
Error in getMethod(“randomForest”) :
no generic function found for ‘randomForest’
function (x, …)
For other functions like classify_polarity() I could get the complete source code just by typing classify_polarity after importing the library (which is sentiment in this case).
