Changing cmultRepl function's behaviour drastically in a patch release?

[heloint]

As the z.warning parameter indicates it should be a warning, not including any sort of actions, such as implicitly deleting registers from the dataset if it's above the given z.warning threshold.

Dear heloint, thanks for your feedback. Such behaviour was actually requested by a number of users to facilitate the embedding of zCompositions routines in data processing pipelines. We have now revised the implementation by including a second logical argument z.delete that allows the user to control for the particular action taken (either delete or just give warning) when z.warning identifies cases. This is available from version 1.5 that its currently on its way to CRAN. Best wishes.
