Is there a function for scatter3d with Categorical responses?
...categorical response instead of a continuous one
library(car)
library(rgl)
scatter3d(prestige ~ income + education | type , surface=FALSE,
ellipsoid=TRUE, revolutions=3, data=Duncan)
Using my data I'd like to use the function as follows:
scatter3d(CSSS$VegtypeID ~ CSSS$MeanAnnualDepth + CSSS$Hydroperiod +
CSSS$MedianWet, ellipsoid=TRUE, revolutions=3, data=CSSS)
or:
scatter3d(CSSS$DA7Depth ~ CSSS$MeanAnnualDepth + CSSS$Hydroperiod +
CSSS$MedianWet | type=CSSS$VegtypeID, ellipsoid=TRUE, revolutions=3,
data=CSSS)
If you know of a different function / package combination that can handle
this app...

logistic regression with repeated measures for species-habitat associations
Hi,
I have three years of species presence/absence data for a set of ~100
ponds, with a list of associated habitat characteristics (park, vegetation,
hydroperiod, etc.). The datasets differ slightly by year because some ponds
were dry in some years and not in others. My goal is to look at habitat
associations for a couple focal species.
For each year, I have a data table that looks like (an expanded version of)
this:
