R and stat noob here. I have been playing with Jeromy Anglim's code in his blog post here. However, my
items$variable has some missing values. I tried using the
distractor.analysis function from the
CTT package with
I get the error
Error : missing values and NaN ’s not allowed if ’na .rm ’ is FALSE
Is there a work-around for using
distractor.analysis for data with missing responses or is there a better way to perform distractor analysis in R?
