I sometimes get this error while running an anova.mppm after fitting mppm models, but then I also get the anova table output along with it, which looks fine. I am wondering if it is okay to use the anova results for my analyses even if I get this error.
Please check that you are using the current releases of the spatstat
packages.
This type of error occurred with previous versions of spatstat
but was fixed in spatstat.core 2.4-1
.
I cannot reproduce this error using the current release of spatstat.core
(2.4-2).
In case you still get this error after installing the latest releases, there could be a problem with the R installation. Then I suggest you start R and type library(spatstat); sessionLibs()
to see which versions are actually loaded.
