R help - Mar 2017 - find index in a list of list

Hi all,

I have a list of lists like this :

mylist <-
list(list(a=10,b="x"),list(a=11,b="y"),list(a=12,b="z"))

I want to find the index of list in mylist where a = 11 and b  = "y" 
, so I want to get 2 as a result

Thanks in advance

Hello,

Something like this?

find <- list(a=11,b="y")
which(sapply(mylist, identical, find))

Hope this helps,

Rui Barradas
