Data Sets

Usage

data(..., list = character(0), package = c(.packages(),.Autoloaded),
     lib.loc = .lib.loc)

Arguments

... a sequence of names or character strings
list a character vector
package a name or character vector giving the packages to look into for data sets. By default, all packages in the search path are used.
lib.loc a character vector of directory names of R libraries. Defaults to all libraries currently known.

Description

data loads or lists available data sets. The data sets to be loaded can be specified as a sequence of names or character strings, or as the character vector list, or as both.

If no data sets are specified, the available data sets are displayed.

Currently, four formats of data files are supported:

  1. files ending ".RData" or ".rda" are load()ed.
  2. files ending ".R" or ".r" are source()d in.
  3. files ending ".tab" or ".txt" are read using read.table(..., header = TRUE), and hence result in a data.frame.
  4. files ending ".csv" are read using read.table(..., header = TRUE, sep=";"), and also result in a data.frame.

Value

A character vector of all data sets specified for loading.

data(package = base)         # list the data sets in the base package
data(crimes, "deaths")       # load the data sets `crimes' and `deaths'
help(crimes)                 # give information on data set `crimes'
