R: Grouping variable(s) for various functions

groups {quanteda} | R Documentation

## Grouping variable(s) for various functions

### Description

Groups for aggregation by various functions that take grouping options.

### Arguments

`groups` | grouping variable for sampling, equal in length to the number of documents. This will be evaluated in the docvars data.frame, so that docvars may be referred to by name without quoting. This also changes previous behaviours for `groups`. See `news(Version >= "3.0", package = "quanteda")` for details.
`fill` | logical; if `TRUE` and `groups` is a factor, then use all levels of the factor when forming the new documents of the grouped object. This will result in a new "document" with empty content for levels not observed, but for which an empty document may be needed. If `groups` is a factor of dates, for instance, then `fill = TRUE` ensures that the new object will consist of one new "document" by date, regardless of whether any documents previously existed with that date. Has no effect if the `groups` variable(s) are not factors.
