I have a "result":
> hazards
(60, 70] (70, 80] (80, 90] (90, 100]
[1,] 0.046612937 0.115643783 0.273613266 0.450127975
Two issues: (i) Too many decimals, and (ii) it seems to be an 1x4
matrix, I only need the first row. (i):
> haz <- round(hazards, 3)
> haz
(60, 70] (70, 80] (80, 90] (90, 100]
[1,] 0.047 0.116 0.274 0.45
As expected, the fourth element lost a trailing zero. I'll deal with
that, but first (ii):
> haz[1, ]
(60, 70] (70, 80] (80, 90] (90, 100]
0.047 0.116 0.274 0.450
And the trailing zero is mysteriously recovered!
Is there some general rule governing this behaviour?
Thanks, Göran
