R help - May 2004 - R-help

Hi,
I have begun to use R some months ago. I have solved many problems, but now
I do not reach my aim.
I have written a function ?Tranmer.cor? with the parameters x, y and N, which
calculates weighted correlation coefficients. It works, when I define the
parameters each time I want to run it. But I cannot tell ?Tranmer.cor? that
it works trough a whole matrix, so that I get a correlation matrix with all
the combinations of variables I have in my data.frame.
There must be a little thing that I have not checked yet.
Thanks for your advice.

If you want pairwise correlations for the cols of matrix x and N
is some parameter to your routine that does not vary throughout
the calculation then:

apply(x,2,function(a)apply(x,2,function(b)Transmer.cor(a,b,N)))

Replace both occurrences of 2 with 1 if you want rows.
