R help - Jul 2007 - how to determine/assign a numeric vector to "Y" in the cor.test function for spearman's correlations?

Hello to all of you, R-expeRts!
I am trying to compute the cor.test for a matrix that i labelled mydata
according to mydata=read.csv...
then I converted my csv file into a matrix with the 
mydata=as.matrix(mydata)
NOW, I need to get the p-values from the correlations...
I can successfully get the spearman's correlation matrix with:
cor(mydata, method="s", use="pairwise,complete,obs")
but then if I try the 
cor.test(mydata, method="s", use="pairwise.complete.obs")
i always get an error message as follows:
the "y" argument is missing and does not have any default value
assigned...
(excuse my translation)
WHAT SHOULD I DO???
HOW CAN I DEFINE "Y" AS A NUMERIC VECTOR???????????
thanx guys, i just can't express myself as a computer would...
G :)

You have to specify two vectors for the test, e.g.:

   cor.test(mydata[,1], mydata[,2], method = "s",
     use = "pairwise.complete.obs")

See the help page ?cor.test
