Hello, I am using function "lambdahat" in "spatialkernel" for my data analysis. I meet a problem. I find under WinXP and Win7, when my code runs to the line of function "lambdahat", R will shut down, without any error message. Sometimes, it does work for 1 or 2 times. However, if I try continuously, R will shut down. The strange thing is that if I try the code under Linux system, it works very well. Does anyone know why? Below is my code: library(spatstat) library(spatialkernel) pol=c(0, 1, 1, 0, 0, 0, 1, 1) dim(pol) = c(4, 2) aa = rpoispp(100) bb = density(aa) cc = as.matrix(data.frame(gx = aa$x, gy = aa$y)) loci = matrix(ncol = 2, nrow = 16384) loci[,1] = rep(bb$xcol, each = 128) loci[,2] = rep(bb$yrow, times = 128) lam = lambdahat(pts = cc, h = 0.1, gpts = loci, poly = pol) Regards, Vincent -------------- next part -------------- An HTML attachment was scrubbed...
