Need help imputing missing values (MICE package)

Hi all. Would anyone please be willing to guide me through the steps of imputing missing data in my data frame? The R package for this is MICE, for multiple imputations.

I don’t know much about data science. I hate to ask for help and believe in learning these things, but I really need to carry out this multiple imputation for my PhD. It’s too far above my beginner-level to do alone, and I am under time pressure.
