In R, vector indexing starts at one; zero are silently ignored.

If I modify the code in the following way
m = ro.r['matrix'](range(4), nrow=2, ncol=2)
idx = ro.IntVector([1,4])
m2 = m.assign(idx, 33)
print(m2)
I get the following matrix
[,1] [,2]
[1,] 33 2
[2,] 133
I think the indices are like vector indices here, a single index, In
