| demo {utils} | R Documentation |
demo is a user-friendly interface to running some demonstration
R scripts. demo() gives the list of available topics.
demo(topic, device = getOption("device"),
package = .packages(), lib.loc = NULL,
character.only = FALSE, verbose = getOption("verbose"))
topic |
the topic which should be demonstrated, given as a
name or literal character string, or a character string,
depending on whether character.only is FALSE (default)
or TRUE. If omitted, the list of available topics is
displayed. |
device |
the graphics device to be used. |
package |
a character vector giving the packages to look into for demos. By default, all packages in the search path are used. |
lib.loc |
a character vector of directory names of R libraries,
or NULL. The default value of NULL corresponds to all
libraries currently known. If the default is used, the loaded
packages are searched before the libraries. |
character.only |
logical; if TRUE, use topic as
character string. |
verbose |
a logical. If TRUE, additional diagnostics are
printed. |
If no topics are given, demo lists the available demos. The
corresponding information is returned in an object of class
"packageIQR". The structure of this class is experimental. In
earlier versions of R, an empty character vector was returned along
with listing available demos.
