h2o.substring

Substring


Description

Returns a copy of the target column that is a substring at the specified start and stop indices, inclusive. If the stop index is not specified, then the substring extends to the end of the original string. If start is longer than the number of characters in the original string, or is greater than stop, an empty string is returned. Negative start is coerced to 0.

Usage

h2o.substr(x, start, stop = "[]")

Arguments

x

The column on which to operate.

start

The index of the first element to be included in the substring.
