Hi Daniela,
Spencer (? Graves) is not at home. Seriously, this is a list that many
people read and use. If you wish to elicit a response, then you would be
wise to give a better statement of what your difficulty is.
The function you enquire about is well documented with an example, see
##
library(GenKern) ## load the package
?KernSur ## get help on the function
You don't need to do anything special to get adaptive bandwidths, it's
all
done for you (by the authors of the package). Just replace the x and y
values in the example with your values, and perhaps deal with any NAs in
your data set.
Should one moralize?: Well, it is generally true that you want help from
others...
HTH, Mark.
