data {base} | R Documentation |
data
loads a data set or lists (via show.data
)
the available data sets.
data(..., list = character(0), package = c(.packages(),.Autoloaded), lib.loc = .lib.loc) show.data(package = c(.packages(),.Autoloaded), lib.loc = .lib.loc)
... |
a sequence of name s 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. |
Currently, four formats of data files are supported:
load()
ed.
source()
d in, with the R working directory changed
temporarily to the directory containing the respective file.
read.table(..., header = TRUE)
, and hence result in
a data frame.
read.table(..., header = TRUE, sep = ";")
,
and also result in a data frame.
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.
If no data sets are specified, data
calls show.data
.
show.data
looks for a file `00Index' (failing that the
deprecated convention of `index.doc') in a `data'
directory of each specified package, and uses these files to prepare
a listing. If there is a `data' area but no index a warning is
given: such packages are incomplete.
data()
returns a character vector of all data sets specified,
an empty character vector if none were specified.
