Rgb (version 1.5.1)

findDrawables:

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.

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.

Details

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