Hi Adrian, you are right, the latest version does not behave like that. Thanks a lot Caspar On Mon, Sep 27, 2010 at 11:57 AM, Adrian Baddeley

I have been found guilty of having NA values in my covariate-images (a categorical variable), and have thus been receiving a lot of warnings.
Having fitted my model and in attempt to print a summary (or the ppm model) my screen is cluttered with
?> ..$ na.covariates:List of 3
? .. ..$ covnames.na ?: chr "habitat"
?> ?.. ..$ quadpoints.na: logi [1:4219, 1]
? ? ? ? ? ? ?FALSE FALSE FALSE FALSE FALSE FALSE ... ?.. ..$ print ? ? ? ?: chr "Values of the covariate ?habitat? were NA or undefined at 7.8% (327 out of 4219) of the quadrature points"
replicated uncountable times, and not allowing me to see any of the useful results.
