findDrawables {Rgb}

Find drawable objects in memory

Description

This function searches an environment for drawable-class inheriting objects.

Usage

  findDrawables(varNames = NA, envir = globalenv())

Arguments

varNames

Character vector, the R expression(s) of potential drawable-class inheriting objects (or lists of such objects) to check. If NA, an object name list will be generated from envir. Non-NA values are mainly used for internal recursive calls on lists, users should not have to change it.

envir

The environment to look into for drawable-class inheriting objects.

Details

Objects are currently found if defined as individual variables, as parts of drawable.list objects or into standard R lists. lists are explored recursively, so lists embedded into other lists are explored too, whatever their depths.

Value

Returns a character vector containing the R expression(s) to be evaluated in envir to get the drawable-class inheriting objects.

This vector carries an "envir" attribute containing the value passed to this function via the envir argument.
