option 3 is possible but probably needs a fix. Alternatively, you can use print(toString(M)) which is implemented similar to the matrix toString().

Suppose I have the following 2x2 csv file: one,two three,four I read it in with: M = read($Min, data_type='frame', format='csv'); (1) If I try: print(M[1,1]); I get: ERROR: null -- line 1, column 0 -- print statement can only print scalars (2) If I try: print(as.scalar(M[1,1])); I get: ERROR: null -- line 2, column 7 -- Expecting matrix parameter for function CAST_AS_SCALAR (3) If I try: print(as.scalar(as.matrix(M[1,1]))); I get: file:/.../src/test/scripts/org/apache/sysml/api/mlcontext/one-two-three-four.csv not a SequenceFile Thanks, Deron
