data.frame_tidiers: Tidiers for data.frame objects

In tidymodels/broom: Convert Statistical Objects into Tidy Tibbles

Tidiers for data.frame objects

Description

Data frame tidiers are deprecated and will be removed from an upcoming release of broom.

Usage

## S3 method for class 'data.frame'
tidy(x, ..., na.rm = TRUE, trim = 0.1)

## S3 method for class 'data.frame'
augment(x, data, ...)

## S3 method for class 'data.frame'
glance(x, ...)

Arguments

x	A data.frame
...	Additional arguments for other methods.
na.rm	a logical value indicating whether NA values should be stripped before the computation proceeds.
trim	the fraction (0 to 0.5) of observations to be trimmed from each end of x before the mean is computed. Passed to the trim argument of mean
data	data, not used

Details

These perform tidy summaries of data.frame objects. tidy produces summary statistics about each column, while glance simply reports the number of rows and columns. Note that augment.data.frame will throw an error.

Value

tidy.data.frame produces a data frame with one row per original column, containing summary statistics of each:

column	name of original column
n	Number of valid (non-NA) values
mean	mean
sd	standard deviation
median	median
trimmed	trimmed mean, with trim defaulting to .1
mad	median absolute deviation (from the median)
min	minimum value
max	maximum value
range	range
skew	skew
kurtosis	kurtosis
se	standard error

glance returns a one-row data.frame with

nrow	number of rows
ncol	number of columns
complete.obs	number of rows that have no missing values
na.fraction	fraction of values across all rows and columns that are missing

glance(mtcars)

library(ggplot2)
# compare mean and standard deviation
ggplot(td, aes(mean, sd)) + geom_point() +

     scale_x_log10() + scale_y_log10() + geom_abline()
