I would like to know if it is possible to make a function that defines a
variable in another function without setting that variable globally?
I would i.e. be able to define a variables value inside a function ("one
level above) which another function makes use of, without setting this
variable globally.
I have provided this very simple illustrating example.
test1=function(x)
{
x+y
}
test2=function(y1)
{
y=y1
test1(2,y1)
}
Running the second function results in an error:
> test2(1)
Error in test1(2) : object 'y' not found
I see 2 possible solutions to this, but neither of them is preferred in my
more complex situation:
1. Setting y<<-y_1 globally in test2-function
2. making test1 a function of both x and y.
Is there any other way to do this except from the 2 above? I hope someone
can help me with this.
