error with bbox for k12hat (splancs) bivarite k-function

redskins80
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!
- Elise

Hi Elise,
I think it's the extra right parenthesis after "okpoly".

I have tried removing a parenthesis to the right of poly and I get this error:

Error in bboxx(bbox(as.points(poly)), nsim = 29, s = seq(5, 80, 5)) :
  unused argument(s) (nsim = 29, s = seq(5, 80, 5))

It looks like you have  one comma for poly, one for as.points, and one for bbox. The original error was due to the first comma... The code itself was from the example() function, so I am not sure why it won't run.
