Hi Sir
When we use Kendall Package to obtain Kendall's Tau statistic.
Then we also get two-sided p value. What does two-sided p-value mean?
The word two-sided is confusing to understand.
Kindly provide help in this regard.

It would be helpful to give an example of what you would like to extract.
I guess you know how to extract elements from vectors and lists.
However, sometimes the objects returned by functions can be rather complex
(output of coxph() is...)
A general method to capture printed output is
Hi,
I recently discovered the R program and I thought it could be useful to me.

18 lines at the beginning that I have to skip). New files are generated
everyday.
This is my strategy :

I realized that my first message and the script were (maybe) too long and

So I tested this shorter one :

Hi All,
I really like to thank you for the answers, while I was searching for some

I thank you for your fast answer.
In order to follow your advices :

The first time, as tfichiers.rda didnt' exist,
