Standard Julia capabilities

Similar to functions in other languages, Julia can perform most of the rudimentary statistics on your data using the describe function, as in the example script that follows:

using RDatasets
describe(dataset("datasets", "iris"))

This script accesses the Iris dataset and displays summary statistics on the dataset.

If we were to build a notebook to show describe in use against the iris dataset (loaded in the previous example), we would end up with a display like this:

You can see the standard statistics generated for each of the variables in the dataset. I thought it was interesting that the count and percentage of NA values in the dataset are provided. I have found that I usually have to double-check to exclude this data using other languages. Here, it is a quick, built-in reminder.
