writing function
Dear group,
I am trying to write functions, but as a beginner, everything is not so
obvious.
Let's say I want the results in a list of elemts like this :
tot1, tot2, etc
Here is a function:
toto <-
function(x,y)
{
for(i in x:y){
paste(c("tot",i),collapse="")<-(i*2)
}
}
If I type this :
>toto(1,5)
I get this message error:
Error in paste(c("tot",

writing function:loop and rbind
Dear group,
I have a function, let's call it myfun, wich give me a list of result:
R1,R2,R3...
There is a loop in this function to get my results. Here is the structure of
my function:
Myfun<-function()
{
For (i in X ){
-----------instructions---------
Ri
{
{
All Results (R1,R2...) are Data.frame. As a final result (call it "Final"),
I need to rbind all these dataframe. One

Re: aec
To everyone on the list: do *NOT* attempt to do echo cancellation with
signals sampled using different clocks. This will *NOT* work. Just a
0.1% difference between the two sampling rates (it's sometimes worse
than that) means that the impulse response drifts by 8 samples every
second. There's just no way to efficiently track this. Or at least no
way that doesn't involve something 100x
