Creating a list from all combinations of two lists
...y I have two lists of arbitrary elements, e.g.:
list1=list(c(1:3),"R is fun!",c(3:6))
list2=list(c(10:5),c(5:3),c(13,5),"I am so confused")
I would like to produce a single new list that is composed of all
combinations of the "top level" of list1 and list2, e.g.:
listcombo=list(list(list1[[1]],list2[[1]]),list(list1[[1]],list2[[2]]
),...,list(list1[[length(list1)]],list2[[length(list2]]))
What is the most efficient way to do this? Thanks!
