...you should use: M <- do.call(union.owin, windows) But that's rather off the track. What I think you should do (it's hard to be certain without a reproducible example) is something like: tw <- tess(tiles=windows) iw <- as.im(funxy(as.function(tw,values=vvv),W=Window(tw)),dimyx=128) where "vvv" is a vector of the values that you wish to associate with the individual polygons. There may be less cryptic ways of accomplishing the same thing, but this is the sexiest way, I think. The value chosen for "dimyx", i.e. 128, is just by way of example. You...

Dear all, I am currently working with the spatstat package, using windows and pixel images. First: My aim is to transform a shapefile (see attached) into a pixel image. My idea is to start transforming the shapefile into a Spatial Polygon file: x <- readShapeSpatial("200001441.shp") y <- as(x, "SpatialPolygons") z <- as.owin(y) Given z, I want to identify each

Hi! I would like to divide a 401 by 401 image into 20 equal blocks and then re-plot the image with the segments randomly distributed in it. How can I do this? ............. Regards, Kenduiywo Benson [[alternative HTML version deleted]]

Hi I am running analysis with Kcross from the package spatstat and I am getting a message that R can not allocate enough memory for a vector of 900MB. R seems to be running towards the 2GB limit per process. The dataset is not to big (ca 3000 points) but the mask for the points is extremely irregular (a buffer around roads which have been sampled) and I can do trhe analysis if I use a

Dear list, are there any possibilities to fill a polygon with a point pattern or with a symbol pattern like '+' oder '-' instead of shading lines?
