I am interested in making a random sample from a uniform distribution of points over the surface of the earth, using the WGS84 ellipsoid as a model for the earth. I know how to do this for a sphere, but would like to do better. I can supply random numbers, want latitude longitude pairs out. Can anyone point me at a solution? Thanks very much. -- Russell Senior ``I have nine fingers;

Can some help me spot what I'm doing wrong here. I have two equations, one a michalis-menton eqn and one a straight line. I need to work out where they cross. I created the function: solveEqn<-function(x,vals){ Vmax<-vals[1] Ks<-vals[2] m<-vals[3] c<-vals[4] diff<-0 mmVal<-exp(Vmax+x/(Ks+x)) slVal<-x*m+c diff<-mmVal-slVal return(diff) } >
