Value

An object of class "overview". Under the hood this is just a list of data frames. Key summary statistics are reported in each data frame.

Arguments

x

A vector or data frame.

hist

Should in-line histograms be returned? Default is FALSE.

digits

How many decimal places should the summary statistics be printed as? Default is 2.

Details

No rounding of statistics is done except in printing which can be controlled either through the digits argument in overview(), or by setting the option options(cheapr.digits).
To access the underlying data, for example the numeric summary, just use $numeric, e.g. overview(rnorm(30))$numeric.

Examples

library(cheapr)
overview(iris)

# With histograms
overview(airquality, hist = TRUE)

# Round to 0 decimal places
overview(airquality, digits = 0)

# We can set an option for all overviews
options(cheapr.digits = 1)
overview(rnorm(100))
options(cheapr.digits = 2) # The default
