2004-03-12 * abind(): allow first argument to be a list of objects to be bound -- this avoids the need for do.call() when one wants to bind a list of objects * abind(): changed default value for 'make.names' to FALSE (now more closely behaves like rbind() and cbind()) * abind(): changed argument name 'use.anon.names' to the more intuitive 'make.names' * adrop(): added new function adrop()
