Categorical data

These functions can be accessed by right clicking on a column and choosing 'Create categorical'.

The following are available:

• numbered data can be re-binned into labelled categories
• string data re-labelled as numbers
• by default calling this function will change the column type to a pandas 'categorical' which can use much less space when saving the table
• dummy binary values can be created from appropriate data (i.e. string labels)
