dc_connective: Extract Connective Discourse Connectors in Context
In trinker/discon: Discourse Connectors Analysis

Description Usage Arguments Details Value References See Also Examples

dc_connective - Extract connective discourse connectors (i.e., "and", "but", & "or" collectively termed discourse connectives (Schiffrin, 1987)) in context.

dc_connective_sub - Extract connective discourse connectors ("and", "but", & "or") in context.

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

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

`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 connective discourse connectors. Use `c("", "")` to not mark the connective 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`.

Schiffrin (1987) describes the funtion of these three coordinating conjunctions:

and has two roles: it “coordinates idea units and it continues a speaker's actions” (p. 128). The speaker may use to “maintain the status quo” (p. 181).
but is used to contrast ideas or actions; in the second form "but" can replace "however" and "anyway" though they can't repace one another (p. 164). The speaker may use "but" to return to an idea or “prior state” (p. 181).
or is used to provide ideas or options.

While "and" and "but" are more speaker centered, "or" is more hearer centered.

dc_connective - Returns returns a list of 2:

`counts`	A `termco` object of connective discourse connector counts.
`connective`	A `trans_context` object of connective discourse connectors in context.

dc_connective_sub - Returns returns a list of 4:

`counts`	A `termco` object of connective discourse connector counts.
`and`	A `trans_context` object of "and" discourse connectors in context.
`but`	A `trans_context` object of "but" discourse connectors in context.
`or`	A `trans_context` object of "or" discourse connectors in context.
