Thank you all for the quick responses.
Setting 0 with *NA* is the right thing to do.
Also Peter, thanks to your package, using the command 'cos <-
cor(m,method='pearson',cosine=TRUE,use='p')' you mentioned' makes my life a
lot more easier.

Hello,
I have a self-defined function to be computed on each column in a matrix.
The basic idea is to ignore the elements that have value of 0 during
computation.
I should be able to write my own function but it could be computational
expensive, so I'd love to ask if anyone may have suggestions
I just realize this:
For myVar1, I used colnames to name it firstly, and then convert myVar1 to
numeric;
However, I forgot to use rownames to name myVar2, instead I thought
as.numeric(names(myVar2)) would work.
Now I name myVar2 using rownames first, as.numeric(names(myVar2)) is
working.
Thank
Hello,
I am using names function to name an array.
It works first time when I use *as.numeric(names(myVar1)*
However, at a place later, when I tried to use a very similar line of code
*as.numeric(names(myVar2)*, it always returned 'numeric(0)' (or if I only
type 'names(myVar2), it gave me NULL'.
That's solved.
Just a cor between X and ti values.
Thank you all.

If someone can help me ?
Thank's a lot

Hello
i need some precision about nipals in the chemometrics package in R .
When i use nipals in chemometrics i obtain T and P matrix.
I really don't understand what to do with these two matrix to obtain
the scores for every the component (like in spss fo example)
