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

Description
data loads or lists via show.data the 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 or
show.data is called directly, the available data sets are
displayed.Details
Currently, four formats of data files are supported:
- files ending
".RData" or ".rda" are
load()ed.
- files ending
".R" or ".r" are
source()d in, with the R working directory changed
temporarily to the directory containing the respective file.
- files ending
".tab" or ".txt" are read using
read.table(..., header = TRUE), and hence result in
a data.frame.
- 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.See Also
help for obtaining documentation on data sets.Examples
data() # list all available data sets
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'
