[R] A Calculation on list object

[Ron Michael]

Hello, I am into some calculation on a list object, therefore requesting the peers if there is any short cut way to so the same calculation.

Let say I have following list object:

> List <- vector('list', length = 3)
> set.seed(1)
> List[[1]] <- rnorm(5)
> List[[2]] <- rnorm(2)
> List[[3]] <- rnorm(7)
> List
[[1]]
[1] -0.6264538  0.1836433 -0.8356286  1.5952808  0.3295078

[[2]]
[1] -0.8204684  0.4874291

[[3]]
[1]  0.7383247  0.5757814 -0.3053884  1.5117812  0.3898432 -0.6212406 -2.2146999

> 
> Vector <- 3:5
> Vector
[1] 3 4 5

Now, what I want to do is, add List with Vector, element-by-element. Means I wanted to do:

> List[[1]] + Vector[1]
[1] 2.373546 3.183643 2.164371 4.595281 3.329508
> List[[2]] + Vector[2]
[1] 3.179532 4.487429
> List[[3]] + Vector[3]
[1] 5.738325 5.575781 4.694612 6.511781 5.389843 4.378759 2.785300

Till now I have done this calculation with for-loop. Therefore it would be interesting if there is any elegant way to do the same.

Thanks,
