Thank you for the reply and suggestion, Michael!
I used dput() and this is the output I can share with you. Simply
explained, I have 3 columns namely, drug_code, freq4w_n and PFD_n. Each
column has 132 values (including NA). The problem with the Wilcoxon Rank
Sum test has been described in my first email.
Please do let me know if you need any further clarification from my
side! Thanks a lot for your time!
