NGRAM

Jan 30, 2018

Syntax

NGRAM(<string, list>;<number for length>;<number for length>;<number for length>;....)

Description

Returns sub sequences of N characters of a given text. To see sub sequences of N words of a given text, refer to NGRAM_OLD. Datameer tries to match entire record without automatically adding ^ or $ to the regular expression. But if the record has multiple lines, then this must be accounted for with (?s) or line terminators.

Example

Data (string)
Datameer is the best.

NGRAM(#RawData!StringColumn;3)

NGRAM() returns
Dat
ata
tam
ame
mee
eer
er
r i
