R markdown link is not formatted blue when knitted to pdf

for some reason no link in my R markdowns (rmd) is formatted blue. knitting the simple rmd below to pdf is leaving the text color black. only when hovering over it does one realize that it's actually a link. knitting it to html will make the link blue. of course I can use a latex wrapper but I wonder why that is?
