count_se: tally/count standard interface.

In WinVector/seplyr: Improved Standard Evaluation Interfaces for Common Data Manipulation Tasks

tally/count standard interface.

Description

Add a new column named "n" with (optionally per-group) sums/counts.

Usage

count_se(x, groupingVars = NULL, wt = NULL, sort = FALSE)

Arguments

x	data.frame to tally/count
groupingVars	character vector of column names to group by.
wt	character optional column name containing row-weights (passed to count/tally)
sort	logical if TRUE sort result in descending order

Details

Note: dplyr::count, dplyr::add_count, dplyr::tally, and dplyr::add_tally are not S3 methods, so it may not be practical to re-dispatch seplyr calls to these dplyr implementations.

Value

.data with added column n, containing counts.
