# [R] How can I use the rho value in the cor.test() summary?

```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.
