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
name
s 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

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'
