Learning about Data in R with str()

Steven Sanderson explains the value of the str() function:

In a nutshell, str() stands for “structure” and offers a concise summary of the structure of an R object. It presents essential details about the object, including its data type, dimensions, and the first few values. By providing an overview of your data, str() allows you to grasp the fundamentals at a glance and proceed with a clearer understanding of what you’re working with.

str() is a really useful function and people who develop objects in R thoughtfully can pack a lot of useful data into the one call.
