[Rd] tag \href not recognised in rd doc

[Patrick Giraudoux]

Hi,

I have a trouble trying to use \href in a rd doc. See example below:

\references{

\href{http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2702787/}{Vaniscotte 
A., Pleydell D., Raoul F., Quere J.P., Coeurdassier M., Delattre P., Li 
T., Qian W., Takahashi K., Weidmann J.C., Qiu J., Giraudoux P. 2009 
Modelling and spatial discrimination of small mammal assemblages: an 
example from western Sichuan (China). Ecological Modelling, 220: 1218-1231.}

}


The Rcmd check gives:

* checking R code for possible problems ... OK
* checking Rd files ... WARNING
checkRd: (7) multignome.Rd:38: Tag \href not recognized

I saw there is already a link on the issue 
http://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14535, but I hardly 
understand if it is a real bug, if so if it have been fixed, or if I am 
misusing the tag...

Any hint appreciated,

Best,

Patrick
