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
