re: lines(lowess())
beginner's mistake on my part. the fitted turned out to have negative values
in it, so the logplot failed. apologies.
it still would be nice to have more docs on lowess, but this has nothing to do
with my question.

Using vectors of names in calls for functions
...s I want to call it from my function.
and I also understood that the "get()" way and the vector of names are
not the good way to adress this.
but I was not able to use/generalise the examples so far discussed on
this list :
mytable <- function(x,y) eval.parent(substitute(table(x,y)))
logplot <- function(y, ylab = deparse(substitute(y))) {
ylab
y <- log(y)
plot(y, ylab = ylab)
}
to achieve my problem.
but i I would be very happy if you could help me on this.
Best regards

Evaluation of defaults in functions
Hello,
and sorry if this is already explained somewhere. I couldn't find anything.
R (2.3.1, Windows) seems to perform some kind of lazy evaluation when
evaluating defaults in function calls that, at least for me, leads to
unexpected results. Consider the following, seemingly equivalent functions:
> foo1 <- function(x, y=x) {
+ x <- 0
+ y
+ }
> foo1(1)
[1] 0
> foo2
