Hi,
Could you please tell me how to access the elements of a S4 object?
Slot "alpha.name":
[1] "Cutoff"
p...@alpha.values
[[1]]
[1] Inf 0.991096434 0.984667270 0.984599159 0.983494405
0.970641299 0.959417835 0.945548941 0.943432189
If that is the print() result of:
p...@alpha.values # then it's probably an ordinary list with a
single vector element, so just try
p...@alpha.values[[1]][2]
(The str function also works on S4 objects .)

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.
