[R] Problem of Running Simulations for Monte Carlo Spatial Segregation Test using Spatialkernel Package
Hello, When I used "spseg" function in the spatialkernel package to run Monte Carlo spatial segregation test, R would not let me run more than 50 simulations. That is, I tried to run the following code, sp <- spseg(pts, bin, hcv, opt=3, ntest=1000, poly=polyb) where pts was a 116*2 matrix containing lat/long; bin was a vector containing categorical types with length of 116; hcv was the selected bandwidth; polyb was a 4*2 matrix which would form a rectangle. But R immediately gave an error message "cannot locate vector of size". I used gc() but it would not help. I could only make it work when ntest=50 or less. Any suggestion is appreciated. Wei Zhang
