Possible source of confusion in Occurrence help page #14

@chfleming

In the Help page of "Calculate a Kriged occurrence disribution estimate", you use "UD" in the example. Would it help the users not confuse the occurence distribution with e.g. akde or bb UD, if you wrote "OD" instead of UD?

Examples

Load package and data

library(ctmm) data(buffalo) Cilla <- buffalo$Cilla

GUESS <- ctmm.guess(Cilla,interactive=FALSE) FIT <- ctmm.fit(Cilla,GUESS)

Compute occurence distribution

UD <- occurrence(Cilla,FIT)

Plot occurrence UD

plot(UD,col.level=NA)

The BB UD is also an occurrence distribution though, which you can calculate with this function.

In our papers, we've been using UD as the generic term for either a range (AKDE) or occurrence distribution (BB, Krige).
