Hello!

I have two functions.

The first one prepares the arguments for the second one. What is the best way to put all resoults of the first one into the second one? I tried attach, however the object in the "main" enviorment have a priority over the ones in list. An example is at the end.

Thanks in advance for any suggestions!

For example - I would like to use just "a" instead of "list$a" in fuction "second"

first<-function(a,b){
    if(length(a)!=1) a <- a[1]
    if(length(b)!=1) b <- b[1]

    list(a=a,b=b)
}

second<-function(list,c){

    list$a + list$b + c
}

a<-c(2,3)
b<-4:64
c<-5

res<-first(a,b)
second(res,c)
