_pepred in this package insists on integer arguments; that is what biting. The restriction is documented, but you need to look at the specific help file. I don't know of any arguments for this except convention, but you need to ask the authors.

The command -prvalue- has a -level(#)- option to specify the width of confidence intervals. I wanted to use 97.5% Cis but it would appear that only integer values are accepted? The following syntax tells me that "option level() incorrectly specified" and "invalid syntax" repectively. If this can be reproduced, I will send off an email to the address in the help file.
