Je vous remercie d'avance pour toute aide ?ventuelle.

Hi!
I need to plot two lines on the same graph. I do
plot(x,y)
then
plot(x,z,add=TRUE)
but I get the following warning messages

Equations as arguments to functions
I am trying to pass an equation as an arguement to a function, which seems
pretty straightforward given lazy evaluation.
I constructed the following little test to make sure I sort of knew what I
was doing:
go <- function(X,eq) { C <<- X*2; d <<- eq}
a _ rnorm(100)
go(10,eq=a[.5*length(a)]+C+1)
> C
[1] 20
> d
[1] 21.10551
> a[.5*length(a)]
[1] 0.1055086
Everything
