Bind importance of bigrams

Calculates and binds the importance of bigrams and their synergistic average.

Usage

bind_lr(tbl, term = "token", lr_mode = c("n", "dn"), avg_rate = 1)

Arguments

tbl

A tidy text dataset.

term

<data-masked> Column containing terms.

lr_mode

Method for computing 'FL' and 'FR' values. n is equivalent to 'LN' and 'RN', and dn is equivalent to 'LDN' and 'RDN'.

avg_rate

Weight of the 'LR' value.

Value

A data.frame.

Details

The 'LR' value is the synergistic average of bigram importance that based on the words and their positions (left or right side).
