In this course, you will learn how to use tidyverse tools and the naniar R package to visualize missing values. You'll tidy missing values so they can be used in analysis and explore missing values to find bias in the data.

Question: I would like to perform imputations on a variable such that it is constant within each id.That is var1 can only have one distinct value for each and every id.. One of it is to perform imputations given the number of occurrences of values of an existing variable as well as some other conditions.
