Hi,

 

Could you please tell me how to access the elements of a S4 object?

 

Slot "alpha.name":

[1] "Cutoff"

 

> perf@alpha.values

[[1]]

  [1]         Inf 0.991096434 0.984667270 0.984599159 0.983494405
0.970641299 0.959417835 0.945548941 0.943432189

 [10] 0.938583020 0.932159806 0.930846938 0.912325837 0.911723615
0.907651100 0.905121019 0.890172812 0.890078186

 [19] 0.885179651 0.883431431 0.879459891 0.876086217 0.868751832
0.868331219 0.865639036 0.858970526 0.858876675

 

I need to get the 2nd element of alpha.values, i.e, 0.991996434.  by
using @, I can get the whole array, but just can't get the access to the
elements.

 

Please Help!  Thanks!

 

Sean
