[R] Extract every 2 element for a list which are not equal in length

Hi, a <- c(1:5)b <- c(1:3) c <- 1 d <- 5 e <- list(a,b,c,d) # To extract every 1st element lapply(e,"[[",1) ## Out-put [[1]] [1] 1 [[2]] [1] 1 [[3]] [1] 1 [[4]] [1] 5 #To extract every 2nd element (Need help in this case) lapply(e,"[[",2) ## Expected outcome [[1]] [1] 2 [[2]]
