Hi,
I have a numeric pixel image which I would like to divide into factors for analysis in Spatstat. I have found that I can use cut.im() function to divide the range of pixel values into a series of equal length intervals (e.g. if my pixels values range from 0 to 60, cut.im(X.im,breaks=2) will produce two factors one containing pixel values 0-30 and one containing pixel values of 30 - 60, or thereabouts). However, I would like to specify the pixel value at which the factors are created - e.g. create one factor containing pixel values of 0-5 and another factor containing all other pixel values. I have been struggling to work out how to do this using either cut.im() or cut.default(). Can anyone help?
