Remove empty elements from list with character(0)

Question

How can I remove empty elements from a list that contain zero length pairlist as character(0), integer(0) etc...

list2
# $`hsa:7476         


        

Answer 1

Another option(I think more efficient) by keeping index where element length > 0 :

l[lapply(l,length)>0] ## you can use sapply,rapply

[[1]]
[1] 1 2 3

[[2]]
[1] "foo"
