dc_comparison(text.var, grouping.var, n.before = 1, tot = FALSE,
  n.after = n.before, ord.inds = TRUE, markup = c("<<", ">>"),
  name = "comparison", ...)

`text.var`	The text variable.
`grouping.var`	The grouping variables. Also takes a single grouping variable or a list of 1 or more grouping variables.
`n.before`	The number of rows before the indexed occurrence.
`tot`	logical. If `TRUE` condenses sub-units (e.g., sentences) into turns of talk for that `grouping.var`.
`n.after`	The number of rows after the indexed occurrence.
`ord.inds`	logical. If `TRUE` inds is ordered least to greatest.
`markup`	A character vector of length two indicating the left (element 1) and right (element 2) boundary markers to use to highlight the comparison discourse connectors. Use `c("", "")` to not mark the comparison discourse markers.
`name`	A string indicating the name to search for within the internal data sets, typically the function's name. Generally, for internal use.
`...`	Other arguments passed to `termco`.

Kalajahi, Abdullah, Mukundan, & Tannacito (2012, p. 1667) provide a list of conenctors that indicate comparisons among things. This list has been adapted to include the following search terms (ellipsis indicates arbitrary word/prefix):

"...'s like", "also", "as if", "as though", "as ... as", "equal to", "in relation to", "in the same way", "is like", "less ... than", "matching", "more ... than", "of little difference", "parallel to", "...re like", "resembling", "same as", "similar to", "similarly", "unlike", "was like".

Returns returns a list of 2:

`counts`	A `termco` object of comparison discourse marker counts.
`comparison`	A `trans_context` object of comparison discourse connectors in context.
