This feature is still experimental with dplyr.
See:
https://dplyr.tidyverse.org/reference/mutate.html https://dplyr.tidyverse.org/reference/summarise.html https://dplyr.tidyverse.org/reference/slice.html
We will introduce it until it's stabilized.
OK. Good!.

Problem Description
Hi,
The latest versions of
dplyr
includes an important design change when grouping.group_by()
before an operation (mutate, summarize, etc) and using anungroup()
after completing it.mutate(dataframe, newvar_definition, by = group)
.For your reference Hadley Wikham has recognized recently that using
group_by()
was a design mistake: https://news.ycombinator.com/item?id=30067406Feature Description
So the proposal would be to align
datar
functionality todplyr
by modifying the verbs (mutate
,slice
,summarize
) in order to include a new parameterby
where one can specify the variable/s to use for the grouping.This new functionality would substitute the current
with_groups()
andungroup()
functions.Thank! Carlos.
