Thank you!
However, this does not do exacty what I want. I would like somehow to
modify only the function second.
What happened when you tried my suggestion as
second <- function(l, c) with(l, a + b + c)
? It does work for me.
BTW, I used "list" only to create a "list", it is not one of my
functions.
You used it as a variable within second()!
Thanks again,

I would avoid using 'list' as a function name, as it will confuse people
and might confuse R too.

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)
