Hello. I'm trying to use mpl to compare one spatial pattern with soil variables. I have generated a surface trend for the soil variables and predicted their values for the x,y of my trees - that's fine. I have generated a 'ppp' for my tree data, but when I try to put the 2 together in mpl, I get the following error message:
"Error in as.ppp(X): Can't interpret X as a point pattern" which is odd because when I,in R, ask it to examine my object it reads: "marked planar point pattern: 55 points multitype, with levels = 1 2 3 4 5 6 window: polygonal boundary enclosing rectangle: [4943.5, 5023.4] x [4965.2, 5083.7]" which, as far as I can tell is a ppp. Can anybody shed some light as to why R would not like it? Is it the polygonal boundary? Thanks, Suzanne __________________________________________________________________ New! Unlimited Access from the Netscape Internet Service.
