Hello,
Is it possible to call a function having x arguments with vector
containing the x values of the arguments in it ?
To make myself clearer, I was wandering if from a function f:
> f
function(a,b) a+b
and a vector v which the 2 values of the arguments "a" and
"b":
> v
a b
1 2
> names(v)
[1] "a" "b"
it is possible to call the function f with vector v as the arguments of the
function.
If I use f(v) it returns me an error since v was considered as the value of the
first argument.
Do you any ideas ??
