Subtracting FloatVector from FloatVector using rpy2












0














I am using grf package in R in my Python code with the help of rpy2. However, I am a little confused with a structure that rpy2 returns.



Here I am trying to find the difference of two vectors simply subtracting. If it was just a vector in R, I would simply subtract using -.



But here is my problem:



    pred_w1.rx2("predictions")
Out[92]:
R object with classes: ('numeric',) mapped to:
<FloatVector - Python:0x1c17447e08 / R:0x7fe214bf7c00>
[-0.548409, -0.224735, 0.948285, 0.269825, ..., 0.259327, -0.267804,
0.255273, 0.287592]


pred_w1.rx2("predictions")
Out[93]:
R object with classes: ('numeric',) mapped to:
<FloatVector - Python:0x1c18f02808 / R:0x7fe214bf7c00>
[-0.548409, -0.224735, 0.948285, 0.269825, ..., 0.259327,
-0.267804, 0.255273, 0.287592]


Now when I try to subtract like this:



    pred_w1.rx2("predictions") - pred_w0.rx2("predictions")`


I get this error:



    File "<ipython-input-95-161c70b4f42f>", line 1, in <module>
pred_w1.rx2("predictions") - pred_w0.rx2("predictions")
TypeError: unsupported operand type(s) for -: 'FloatVector' and 'FloatVector'


I think this should be fairly easy. I am just not so familiar with rpy2.
