data_profile: Compact vector profile

In termr: Modern Reactive Terminal Applications with Data Workflows

Compact vector profile

Description

Summarizes numeric/integer, character/factor, logical, Date, and POSIXct vectors. Numeric summaries use base R type-7 quartiles and sample standard deviation (stats::sd). Numeric data also gets an eight-bin histogram rendered with the existing sparkline widget. Without sample, vector summaries analyze the full in-memory vector. Character top-value counts cap their frequency table at 100,000 analyzed non-missing values. Supplying sample analyzes deterministic, evenly spaced positions. A table_source is rejected to prevent an implicit full scan; fetch or sample data explicitly first. data may also be a reactive function.

Usage

data_profile(
  data,
  name = NULL,
  sample = NULL,
  top_n = 5L,
  id = NULL,
  classes = NULL,
  style = NULL,
  disabled = FALSE
)

Arguments

data	An atomic vector, factor, Date, or POSIXct vector.
name	Heading for the profile.
sample	Optional positive number of evenly spaced values to analyze.
top_n	Number of frequent character/factor values to display.
id	Optional identifier.
classes	Optional classes.
style	A style().
disabled	Disable the widget?

Value

A DataProfile widget with reactive ⁠$data⁠ and ⁠$summary⁠.

Examples

data_profile(mtcars$mpg, name = "mpg")
