Dear Patrick,

Assuming that datavector1 is the first column of your data set, you can try:

# Data set

set.seed(123)
y=matrix(rnorm(100*6),ncol=6)
rownames(y)=1:100
colnames(y)=c('datavector1',paste('X',1:5,sep=""))
y[1:10,]

# Correlations
RES=apply(y[,-1],2,function(y,x)
cor.test(x,y,method="spearman")$estimate,y[,1]) RES RES contains the (k-1) spearman correlation coefficient, being k the number of columns of your data.

HTH, Jorge
