I've recently come across this coding exercise but as I've just started learning R, I'm not sure how to solve these. Below is my dataset screenshot,
Below are the queries,
a. What regions have the maximum and minimum total Indigenous populations(given in column 'Value') in 2016 and 2031?
b. What region/s have the maximum and minimum growth or decay rates of their total Indigenous population between 2016 and 2031?
Calculate these rates as the percentage difference between the 2016 and 2031,
e.g., if 2031 population = 5500 & 2016 population = 5000, then rate = (5500 – 5000) / 5000 = 500/5000 = 0.1, so 10% growth
There is a homework policy around here; and it is usually not considered good manners to post your data as a screenshot (what are we supposed to do with it?)
However, to get you started: have a look at chapter 5 of the R4DS book, paying close attention to commands:
arrange() used to sort a data frame according to a column value
filter() to filter data according to a condition
the special case of top_n() used to select the first n rows from a sorted data frame.
to create new variables from existing ones mutate()will be your friend.
