Description

This function describes the variables of a vector or a dataset that might include labels imported with haven packages.

Usage

describe(x, ...)
# S3 method for factor
describe(x, n = 10, show.length = TRUE, freq.n.max = 10,
  ...)
# S3 method for numeric
describe(x, n = 10, show.length = TRUE, freq.n.max = 10,
  ...)
# S3 method for character
describe(x, n = 10, show.length = TRUE,
  freq.n.max = 10, ...)
# S3 method for default
describe(x, n = 10, show.length = TRUE, freq.n.max = 10,
  ...)
# S3 method for labelled
describe(x, n = 10, show.length = TRUE,
  freq.n.max = 10, ...)
# S3 method for data.frame
describe(x, ..., n = 10, freq.n.max = 0)
# S3 method for description
print(x, ...)

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.
