Hi R users, Suppose I have two lists and the names of list 'm' are a subset of those of 'n', how can I sum the two lists with corresponding elements added together to get list 'o'?
n = list("a"=1,"b"=3,"c"=5)
m = list('b'=4)
o
$a [1] 1 $b [1] 7 $c [1] 5 Thanks -- Best, Zhenjiang ? ? ? ?[[alternative HTML version deleted]]
