The following are a sampling of one-liner tests. They provide a wealth of information on any numeric series/column with little code required. If you are doing upfront data exploration, put a chunk of these at the beginning of your program.
18.1 Basic Numeric Vector Tests
For simplicity, let’s use the built-in dataset “Animals.” Using brain size as a numeric variable
, the following code provides plenty of descriptive information. Figure 18-1, a histogram of brain weights, shows that most are less than 1000 ccs. ...
