Hello,
I'm trying to make a 3d plot using rgl in which the size and color of
each point corresponds to certain attributes of each data point. The color

rainbow(64,start=0.7,end=0.1) palette is perfect for what I want but I

Dear R experts:
I have some confusion about vglm function for cumulative logit/probit
models. Does the function checks for parallelism? I was wondering what
happens if we say parallel = FALSE in case of cumulative probit/logit model.
Does vglm fits dichotomous models in that case ?
