Julia for Data Science

Counting functions

In data exploration, counting over a range is often done. It helps to find out the most/least occurring value. Julia provides the counts function to count over a range. Let's say we have an array of values. For our convenience, we will now use the random function to create an array:

We have created an array of 30 values ranging from 1 to 5. Now we want to know how many times they occur in the dataset:

Using the count function, we found that 1(7), 2(1), 3(5), 4(11), and 5(6). counts take different arguments to suit the use case. ...
