Data Sets

Description

data loads a data set or lists (via show.data) the available data sets.

Usage

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

Details

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, with the R working directory changed temporarily to the directory containing the respective file.

  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, an empty character vector if none were specified.

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