summarize {crplyr}R Documentation

Aggregate a Crunch dataset

Description

This is an alternate interface to crunch::crtabs() that, in addition to being "tidy", makes it easier to query multiple measures at the same time.

Usage

## S3 method for class 'CrunchDataset'
summarise(.data, ...)

Arguments

.data

A CrunchDataset

...

named aggregations to include in the resulting table.

Details

Note that while mutate() is not generally supported in crplyr, you can derive expressions on the fly in summarize().

Value

A tbl_crunch_cube or cr_tibble of results. This subclass of tibble allows ggplot2::autoplot to work, but can get in the way in some tidyverse operations. You may wish to convert to a tibble using as_tibble().

Examples

## Not run: 
ds %>%
    filter(cyl == 6) %>%
    group_by(vs) %>%
    summarize(hp=mean(hp), sd_hp=sd(hp), count=n())

## End(Not run)
