  lib.loc = NULL, character.only = FALSE)

`name`	name of snippet
`execute`	a logical. If `TRUE`, snippet code is executed. (The code and the results of the execution will be visible if `echo` is `TRUE`.)
`view`	a logical. If `TRUE`, snippet code is displayed 'as is'.
`echo`	a logical. If `TRUE`, show the R input when executing.
`ask`	a logical (or "default") indicating if `devAskNewPage(ask=TRUE)` should be called before graphical output happens from the snippet code. The value "default" (the factory-fresh default) means to ask if `echo == TRUE` and the graphics device appears to be interactive. This parameter applies both to any currently opened device and to any devices opened by the demo code. If this is evaluated to `TRUE` and the session is interactive, the user is asked to press RETURN to start.
`verbose`	a logical. If `TRUE`, additional diagnostics are printed.
`lib.loc`	character vector of directory names of R libraries, or NULL. The default value of NULL corresponds to all libraries currently known.
`character.only`	logical. If `TRUE`, use `name`as character string.
