How can I use the rho value in the cor.test() summary?

x=c(1,2,3,4,5,6,7,8,9) y=c(3,5,4,6,7,8,8,7,10) z=cor.test(x,y) othervariable=z$p.value Cheers, Daniel ------------------------- cuncta stricte discussurus ------------------------- -----Urspr?ngliche Nachricht----- Von: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] Im Auftrag von Hayes Gesendet: Tuesday, December 04, 2007 2:11 AM An: r-help at r-project.org Betreff: [R] How can I use the rho value in the cor.test() summary?

Spearman's rank correlation rho
data: a[, 3] and a[, 2]
S = 22, p-value = 0.001174
alternative hypothesis: true rho is not equal to 0
sample estimates:
rho
0.8666667

z$statistic, more likely.

My apologies, I was wrong with z$p.value. That is not what you wanted. I should not write email at 3:30 :) But I think z$statistic as suggested by Peter is not it either. You said you want the rho. The code for it is z$estimate, assuming that you used method="spearman" to get a rho . Please look below. It is othervariable3 that you want. So to get it (hopefully) fully right once: x=c(1,2,3,4,5,6,7,8,9) y=c(3,5,4,6,7,8,8,7,10) z=cor.test(x,y,method="spearman") z othervariable=z$p.value othervariable2=z$statistic othervariable3=z$estimate You can get help for the function by typing ?cor.test . This shows you the available values returned by cor.test that you can easily assign to other variables. ------------------------- cuncta stricte discussurus ------------------------- -----Urspr?ngliche Nachricht----- Von: Peter Dalgaard [mailto:p.dalgaard at biostat.ku.dk] Gesendet: Tuesday, December 04, 2007 3:33 AM An: Daniel Malter Cc: r-help at r-project.org Betreff: Re: [R] How can I use the rho value in the cor.test() summary?

, more likely.
