count_groups {fritools} | R Documentation |
I tend to forget the syntax that works with

count_groups(x, ...)
x |
A |

Columns in |
A data.frame
with the counts per groups.
Other statistics:
column_sums()

,
sloboda()
,
weighted_variance()
count_groups(mtcars, "am", "gear")
RUnit::checkEquals(dplyr::count(mtcars, am, gear),
count_groups(mtcars, "am", "gear"), checkNames = FALSE)
