Hi R Experts,
How do you get the ... to work in a user-defined function such as the one I
have below?
For example if I want to pass replace=TRUE to the sample function.
# This is a sample function that generates x rows of z numbers out of y.
Basically a lottery style data set.

Hi,
It's easy, just carry the arguments in '...' forward to where you expect to
pass them along.
mynumbs
numbs - rbind(numbs, sort(sample(y, z, ... )))

Hi Annie,
The error is in the R script...you start reading with Args[1] but instead
you should start with Args[5] etc. because (I believe) that R --slave
--vanilla --args count as
[1] [2][3][4]
Therefore, Args[5] it's the first argument you
Hi Annie,
while I don't use python, I've been in similar positions.
here's a good link for the arguments function. It's the best
example/tutorial I've seen on the topic. It will also help you perhaps to
print the values of the arguments to screen/file within R to see if things
are going okay.
Hi,
I've got an R script that I'm trying to turn into a ArcGis script tool so
that I can run it from ModelBuilder in Arc. Arc isn't giving me any errors
when I run the model holding the current tool, but the run time for the R
script is 0 seconds. I don't know if the parameters aren't being

I knowf R functions ca be called passing some parameters.
My first question is: how are parameters passed to R functions ?
Browsing through R archives I found an answer confirming taht parameters can
be passed to the called function by value. I wonder whether passing the
parameter

No you can not pass an address to a function. If you want to change
the value of something, then return it as a value and assign it to the
object so you can see what is going on. Must be coming from the C
environment where such things are allowed and lead to a number of
problems.
If you really
R's variable passing mechanism is not call by value, but a mixture of
unevaluated arguments (like the obsolete Lisp FEXPR) and call-by-need.
It is like FEXPR in that the function can capture the unevaluated
argument (using 'substitute'). But it is like call-by-need in that
