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,

Subject: [R] pearson correlation significant level
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.
> rcorr(as.matrix(datat), type="pearson") # type can be pearson or
The result is
t_i 1.00 -0.89
t_r -0.89 1.00
