group_indices_se

.data

<p>character vector of column names to group by.</p>

groupingVars

<p>Group a data frame by the groupingVars and add group labels.</p>

The 'seplyr' (standard evaluation plying) package supplies improved
standard evaluation adapter methods for important common 'dplyr' data manipulation tasks.
In addition the 'seplyr' package supplies several new "key operations
bound together" methods.  These include 'group_summarize()' (which
combines grouping, arranging and calculation in an atomic unit),
'add_group_summaries()' (which joins grouped summaries into a 'data.frame'
in a well documented manner), 'add_group_indices()' (which adds
per-group identifiers to a 'data.frame' without depending on row-order),
'partition_mutate_qt()' (which optimizes mutate sequences), and 'if_else_device()'
(which simulates per-row if-else blocks in expression sequences).
