Thanks for the response, sorry I didn't post it initially.
kt.mat <-
function(x,y,z){
for(i in 1:length(x)){for(j in
1:length(y)){z[i,j]<-(y[j]-y[i])/(x[j]-x[i])}}
return(z)}
kt.slope <-
function(x,y,z,s){
count<-0
for(i in 1:length(x)){for(j in 1:length(y)){
if(j >= i+1) {
count<-count+1
s[coun
Also called Sen's slope estimate...

I found some code to compute a Kendall-Theil slope estimate and want to add
it to a scatter plot. Is there a way to make it appear like a regression fit
instead of a line that extends from the edges of the plot? I would like to
have the OLS appear as a dotted line and the KT a solid line but as it
