Dear List,

I have a list of lists and on each list I want to apply a function
from the igraph package, graph.knn. I need to calculate graph.knn for
each list on a graph g, then retrieve one of the result called $knn
and calculate its mean. The non-R style code looks like this:

for(i in listOfLists){
	print(mean(graph.knn(g, i)$knn))
}

Is there any way to convert this in a one-liner? I have tried to
figure it out with lapply() or mapply() but with no success.

Thank you in advance for your help.

Simone
