I got caught out converting a 3d array in R to a numpy array. I did something like:
import numpy import rpy2 import rpy2.robjects as robjects marr = robjects.r.array(robjects.IntVector(range(54)),dim= robjects.IntVector([9,2,3])) marrpy = numpy.array(marr) print marrpy.flatten() print robjects.r['as.vector'](marr) Which clearly doesn't work (at least for me, using rpy2.1.7, R-10.0 on 64bit suse linux). The matrix version does work, eg mat = robjects.r.matrix(robjects.IntVector(range(54)),nrow=9) matpy = numpy.array(mat) print mat print matpy I checked the documentation, and found examples for vectors and matrices, but not for arrays, but also no warnings. So, I was just wondering, is this supposed to work? If it is, a hint on why it doesn't work for me would be good. If it isn't supposed to work, I was wondering if it were possible to throw an error or something.
