This is what I thought, too. But if I link for example to function anova() in pacakge stats, the html link after installing the new package is:

file:///home/adi/myRlibrary/stats/html/anova.html

where the stats package is by default installed in:

/usr/lib/R/library/

(indeed my question was related to Windows too, not only on Linux)

I understand, thank you. I learned from Prof. Ripley's answer that Windows has link.html.help() function to resolve the html help files from all installed packages.

Best wishes,
