Hello All
 
I also ran into some problems when using the package BBMM. When I run this for the first time in an R session: 
 
dat<-data.frame(xx=sort(runif(30,1000,2000)),yy=sort(runif(30,500,1000)))
bbmm <- brownian.bridge(x=dat$xx,y=dat$yy,time.lag=rep(20,nrow(dat)-1),location.error=20,cell.size=50)
bbmm.contour(bbmm,locations=dat,levels=c(60,99))
 
I get NaN for all probabilities in bbmm$probability. When I run it a second time, it works and everything seems OK in the contour plot. In runs after that, the contour plot eventually degrades. So basically in this case R has to be closed and the function ran twice to get good results! Don't know if this could help in identifying the bug.
 
Cheers
