In a 'hospital' collection, there are docs for every department in the hospital. Each document has details like department_name, doctors and nurses assigned for this department. The document structure looks like below:

I have a data table that has four columns: a,b,c,d that I'd like to count the unique combinations of a, b, and c but also record which values of d are in that combo in a new column.

Example of a data.table:

I have table

I am learning R. I know how to join dataframes based on various criteria and using various methods - all of that if they have something in common (e.g. column). But what if they do not?

I have a two example dataframes: df_data and df_categories (code provided below). I would like to modify df_data by adding new columns based on the values in df_categories. The dataframes do not share a common column.

I'm learning some basics of C (I'm actually doing Harvard's cs50x) and I wrote this code:

I have C program that needs to find the position of a number. It goes like this:

From standard input we enter unknown number of number that are positive. The numbers have maximum of 5 digits, we read new numbers till the user enters a value that is not a number. I need to find the positions of the max digit of a number from right to left. Use the right-most position if there are more than one instance of the max digit.

The program needs to output the position and the number of times the max digit of a number was found at that position.

For example:
input:

Suppose I have the following document:

I have the following snippet:

I would like to run a Dunn test with the purrr package. However, the tidy function to extract the parameter/results seemed to do not work with this test. Any one has sugesstion for me?

My example.
