[R] question on how to extract values from atomic vector

[jim holtman]

There are a couple of ways of getting the values:

> x <- cbind(a=1:3, pi=pi) # simple matrix w/ dimnames
> attributes(x)
$dim
[1] 3 2

$dimnames
$dimnames[[1]]
NULL

$dimnames[[2]]
[1] "a"  "pi"


> attributes(x)$dim
[1] 3 2
> attr(x, 'dim')
[1] 3 2
>

So in your case,

attr(Results, 'prob')

or

attributes(Results)$prob
