This function merges information from two frequency lists, subtracting the frequencies found in the second frequency lists from the frequencies found in the first list.
Arguments
- x, y
Objects of class
freqlist.
Value
An object of class freqlist.
Examples
(flist1 <- freqlist("A first toy corpus.", as_text = TRUE))
#> Frequency list (types in list: 4, tokens in list: 4)
#> rank type abs_freq nrm_freq
#> ---- ------ -------- --------
#> 1 a 1 2500
#> 2 corpus 1 2500
#> 3 first 1 2500
#> 4 toy 1 2500
(flist2 <- freqlist("A second toy corpus.", as_text = TRUE))
#> Frequency list (types in list: 4, tokens in list: 4)
#> rank type abs_freq nrm_freq
#> ---- ------ -------- --------
#> 1 a 1 2500
#> 2 corpus 1 2500
#> 3 second 1 2500
#> 4 toy 1 2500
freqlist_diff(flist1, flist2)
#> Frequency list (types in list: 5, tokens in list: 1)
#> <total number of tokens: 0>
#> rank type abs_freq
#> ---- ------ --------
#> 1 first 1
#> 2 a 0
#> 3 corpus 0
#> 4 second 0
#> 5 toy 0
