Dear all,
I'm a newbie to R and I would really apperciate any help with the following:
I have two lists, l1 and l2:
l1:
$"A*0101"
[1] 0.076 0.109 0.155 0.077 0.09 0 0 0.073
[9] 0.33 0.0034 0.0053
$"A*0247"
[1] 0 0 0.5 .004 0 0 0
$"A*0248"
[1] 0 0 0.3 0 0.06
....
l2:
$"A*1101"
[1] 0.17 0.24 0.097 0.075 0.067
$"A*0247"
numeric(0)
$"A*0248"
[1] 0.031
....
Basically, what I want to do is run wilcox.test() on each entry pair
in the list.
1) I want to loop through the list to run wilcox.test for each entry
of the list. How would I do that? mapply()?
wilcox.test(l0[[1]],l1[[1]]) for the first one and so on....
2) I want to exclude the list entry which has no values (i.e. A*0247).
3) Finally, I only want the to see the 'p-value' for each list names.
The output I want capture is only the 'p-value' object from
wilcox.test.
name p-value
A*0101 0.8329
.... ....
I'm grateful for any help, or any pointers to a good online tutorial.
Thanks a lot in advance,
-T.
