hi all,
I have a simple problem that i am not able to solve. I've a list called
datalist with the following structure:
[...]
[[10]]
[[10]]$a
-1 0 1
-1 31 5 2
0 6 7 5
1 1 7 36
[[10]]$b
-1 0 1
-1 31 5 2
0 6 7 5
1 1 7 36
[[10]]$c
[1] 0.855
[[10]]$d
[1] 0.855
[...]
with [[1]] ... [[100]]. How can i get the mean value of datalist[[x]]$d,
where x represents all elements from 1 to 1000 ?
I'd try something like mean(sapply(x,"[[","d"))
