class

datatable.

Type

source

Added in version 1.0.0

Type of data stored in a single column of a Frame.

The type describes both the logical meaning of the data (i.e. an integer, a floating point number, a string, etc.), as well as storage requirement of that data (the number of bits per element). Some types may carry additional properties, such as a timezone or precision.

Note

This property replaces previous dt.stype and dt.ltype.
