Dear list, I am attempting to fit an inhomogeneous poisson point process to some point pattern data, using ppm from spatstat (v 1.17-5). 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. I think I can get around it, but I just wonder if this is the intended behaviour of print.ppm and print.summary.ppm. Thanks in advance Caspar _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
