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:
".RData"
or ".rda"
are
load()ed
.
".R"
or ".r"
are
source()d
in, with the R working directory changed
temporarily to the directory containing the respective file.
".tab"
or ".txt"
are read using
read.table(..., header = TRUE)
, and hence result in
a data.frame
.
".csv"
are read using
read.table(..., header = TRUE, sep=";")
,
and also result in a data.frame
.
A character vector of all data sets specified, an empty character vector if none were specified.
