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.
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.
