Dear Elaine,
One of the elements you obtain the P matrix, which is the matrix of asymptotic
p-values. In your case, you get that the asymptotic p-value of the association
between t_i and t_r is 0. That is, there would exist a perfect association (look
also at the first result, the matrix of correlations: the correlation
coefficient between these variables is 1).
Hope this helps,
Jos?

Subject: [R] pearson correlation significant level
Hello
I am using package Hmisc to calculate the pearson correlation and the
significant level for the matrix of t_i and t_r. (temperature minimum and
temperature range)
However, I have difficulty interpreting the result, even after checking the
manual.
Please kindly help to indicate if the p-value is zero.
Thank you in advance.
Elaine
The code> library(Hmisc)
> rcorr(as.matrix(datat), type="pearson") # type can be pearson or
> spearman
The result is
t_i t_r
t_i 1.00 -0.89
t_r -0.89 1.00
n= 4873
P
t_i t_r
t_i 0
t_r 0>
