...rea? The problem with 'Istat' function is also that it requires both data sets to have the same length, while I would be more interested in a function that enables overlap calculation even if data sets have different length. Looking forward to hearing from you! Have a good day. Ana library(SDMTools) a <- matrix(runif(30)) b <- matrix(runif(30)) Istat(a,b) [[alternative HTML version deleted]]

Dear all I tried to find some packages (or programs) for image analysis and especially fractal dimension image analysis but so far I had not success. It shall be used for particle surface layer analysis from TEM images. Any suggestions? Best regards Petr

...those points are in one of several polygons, as my code overwrites the result. To accomplish this I am using the R-built in function called point.in.polygon. Point.in.polygon takes the x, and y lat/lon points, and the polygon boundaries. Here is the code I've written thus far: require("SDMTools") require("sp") #b is the polygon that I'm referring for (b in 1:9) { D <- subset(Bounds, Polygon == b) for (i in 1:length(Bounds$latitude)) { M = point.in.polygon(Bounds$latitude[i], Bounds$longitude[i], D$PY,D$PX) if (M>1) { Bounds$T[i...

...f this non empty cells, I have to find and keep only a maximum of 10 Male-Female pairs that are within 3 meters from each other. The 3-meter buffer can be done using the "disc" function within spatstat. To select points falling inside a buffer you can use the method pnt.in.poly within the SDMTools package. All that because pixels have a maximum capacity that cannot be exceeded. Since in each cell there can be hundreds or thousands of points I am trying to find a smart way to use another loop/similar method to: 1)go trough each point at a time 2)create a buffer a select points with different...
