LL from bearing and distance

Is there a package that contains a function that will allow me to calculate 
the ending latitude and longitude given a starting point on the earth's 
surface and bearing and distance?  I have searched the archives but have been 
unable to find one and would like to double check before I try to roll my 
own.  Thanks for any pointers.

Nothing for this case - azimuth for two points is in gzAzimuth() in 
maptools, so that might be a way in. There is C code for the spDistsN1() 
function in the sp package, visible in the CVS repository at the r-spatial 
site at sourceforge, but neither of these meets your need directly. If you 
do "roll your own", please consider contributing to maptools.
