[spatstat] Convert shapefile to pixel image
...er than "M <- union.owin(windows)"
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&qu...

[spatstat] Convert shapefile to pixel image
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
