Hello I am going to look at the ZIP (zero-inflated poisson). I just need to ask. One of my variables is continuous data (hosts body length), is it ok to include this kind of data into this analysis or do I need to turn it into categories (29-50 mm, 51-100mm and so on)? Many Thanks Charlotte

Re: [R] help with reshape

I don't think it is platform or version specific. The purpose of the missing value, NA (i.e. Not Available), is to flag the value for special handling in some way, often by deletion. You cannot assume that NA will be treated as any other value since that would defeat the whole purpose of flaggin
