Hi I am running the following locfit function:> fit <- locfit( log(base$Value) ~ base$lBrkOut + base$lExit , alpha=0.9) > plot(fit,type="persp" )The above two steps create a nice 3d plot. I would like to find the xy coordinates where the maximum z occurs. Does any one know of function to call that will display the xy coordinates where max(z) occurs? Thanks Lawrence
You can just do something like base[which.max(predict(fit)),]. One suggestion: Use something like locfit(log(Value) ~ lBrkOut + lExit, data=base, ...). It's much safer that way.
