compute_sentratios_facet_by2: Compute token sentiment log ratios in pairs
In tonyelhabr/tetext: Tony's Personal Package for Text Analysis

Description Usage Arguments Details Value

Apply compute_logratios_facet_wide_at() to data in pairs of facet values, then do post-processing for sentiments.

compute_sentratios_facet_by2_at(data = NULL,
  func = compute_logratios_facet_wide_at, token = NULL, facet = NULL,
  xy_grid, xy_nms, cnt_min = 10, lexicon = "bing", ...)

compute_sentratios_facet_by2(..., token, facet)

`data`	data.frame. Data to apply a function over.
`func`	function. Wrapped by `do.call()`.
`token`	bare for NSE; character for SE. Name of column in `data` to use for count.
`facet`	character. Name of column in `data` to use for facetting. It is set to NULL by default in the non-`facet` function even though it is not necessary. If specified with the non-`facet` version of the function, then the function acts just like the `_facet` version.
`xy_grid`	data.frame. Output from `create_xy_grid()`.
`xy_nms`	character (vector). Values to use to create a 'grid' of all combinations of values.
`cnt_min`	numeric. If not null, serves as a filter for which to compute log ratios.
`lexicon`	character. Specifies lexicon to use. Must be a lexicon available in the `tidytext::package`.
`...`	dots. Adddition parameters to pass to `get_sents()`.

Calls wrapper_func internally. This function is very similar to compute_sentratios_facet_by2_at(), but with some post-processing. Note that ... are passed to get_sents() here (instead of to compute_logratios_facet_wide_at(), so token and cnt_min must be checked for NULL explicilty.

data.frame.
