如何在R中逐元素列出求和

Question

this is very similar to

Is there an R function for the element-wise summation of the matrices stored as elements in single list object?

How can I do list summation element-wise in R?

For example, I want

temp1<-list(c(rep(0,6)),c(1,2,3,4,5,6))
temp2<-list(c(2,3,4,5,6,7))

to yield

 3,5,7,9,11,13     

Just simple temp1[[2]] + temp2 doesn't work. Is there a special formula for it?

Answer 1

我们可以使用Map

Map(`+`, temp1, temp2)[[2]]

Answer 2

Assuming that both the vectors in the list are of same length:

lst=list(a=c(1,2,3,4,5,6),b=c(2,3,4,5,6,7))   
list(mapply(FUN = sum,lst$a,lst$b))'.
