A wild guess is that you have not converted your newdate column into a time metric such as Date or POSIXt. Our responses can be ever so much more helpful if you follow the Posting Guide (mentioned in the footer), e.g. posting using plain text so the code gets through the mailing list successfully, and if you make your example reproducible [1].
