A basic user settings facility, like options and lattice.options.

Keywords
programming
Usage
playwith.options(...) playwith.getOption(name)
Arguments
name
character giving the name of a setting.
...
new options can be defined, or existing ones modified, using one or more arguments of the form 'name = value' or by passing a list of such tagged values. Existing values can be retrieved by supplying the names (as character strings) of the components as unnamed arguments.
Details

These functions are direct copies of the lattice equivalents: see lattice.options.

The available options can be seen with str(playwith.options()). Many of these simply provide defaults for corresponding arguments to the playwith function.

                  text = paste(Sys.time(), Sys.info()["login"],
                               R.version.string, sep = ", "))
    if (!is.na(txt))
        callArg(playState, "sub") <- if (nchar(txt) > 0) txt
})
playwith.options(styleShortcuts = list("mySub" = doMySub))

## try it:
if (interactive())
  playwith(plot(1:10))
