## S3 method for class 'numeric'
describe(x, n = 10, show.length = TRUE, freq.n.max = 10, ...)

## S3 method for class 'character'
describe(x, n = 10, show.length = TRUE, freq.n.max = 10, ...)

## Default S3 method:
describe(x, n = 10, show.length = TRUE, freq.n.max = 10, ...)

## S3 method for class 'haven_labelled'
describe(x, n = 10, show.length = TRUE, freq.n.max = 10, ...)

## S3 method for class 'data.frame'
describe(x, ..., n = 10, freq.n.max = 0)

Arguments

x

...

further arguments passed to or from other methods, see details

n

number of first values to display

show.length

freq.n.max

display a frequency table if the number of unique values is less than this value, 0 to hide

Details

When describing a data.frame, you can provide variable names as character strings. Using the "*" or "|" wildcards in a variable name will search for it using a regex match. The search will also take into account variable labels, if any. See examples.
