Hello,

I am trying to conduct a bi-variate ripley's k using the k12hat function in the splancs package (found here

http://rss.acs.unt.edu/Rdoc/library/splancs/html/k12hat.html). Although, I receive an error when getting to the bboxx part of the code:

poly <- list(x=c(fire4$X, nar4$X), y=c(fire4$Y, nar4$Y))

plot(seq(5,80,5), sqrt(k12hat(fire4), as.points(nar4),

bboxx(bbox(as.points(okpoly))), seq(5,80,5))/pi) - seq(5,80,5), xlab="distance",

Error: unexpected ',' in "bboxx(bbox(as.points(poly))),"

What am I doing wrong? Any help would be greatly appreciated.

Thanks!
