tally/count standard interface.

Source: R/tally.R

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

add_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

Value

.data with added column n, containing counts.

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.
