R help - Feb 2013 - adehabitatHR - Creating Biased Random Bridge UD with a boundary

Dear List,

It's the first time that I try to request your support.

I intent do use the BRB (Biased Random Bridge) function with a boundary.

I believe I have made sure to fulfill all the rules for boundaries (segment
length, angle of junction)

When calculating the UD I get the following Error:


Error in adehabitatHR:::.fbboun(sor2, boundary, sigg, max(so$h)) :    non
convenient sign


Can anyone tell me, what the "clean the other side of the boundary"
procedure does, so I

can get my boundary to be "convenient". :) I just found these lines
(see below) on R-Forge, but unfortunately I do not

understand what I am supposed to do.

Thank you very much in advance,

Kind regards,

Robert 


## clean the other side of the boundary					        

        if (!is.null(boundary)) {						    

            sor2 <- adehabitatHR:::.fbboun(sor2, boundary, sigg, max(so$h))

        }									        

        sor2 <- new("estUD", sor2)						       

        slot(sor2, "h") <- list(values = list(hmin=hmin, D=D),
interp = so,

                                meth = "BRB-specified")

        slot(sor2, "vol") <- FALSE						        


        return(sor2)
