smoothing bathymetry
Dear R Users,
Using the following R-script I created the first image
> require(akima)
> require(spatial)
> dep <- interp(long, lat, depth, xo=seq(1,990,10), yo=seq(1,990,10),
+ extrap=FALSE, ncp=0,duplicate = "mean", dupfun = NULL)
http://r.789695.n4.nabble.com/file/n3431391/Rpics.bmp
Where "long" are x-coordinates between 1 and 1000, "lat" are y-cordinates
between 1 and 1000, and depth are depth values corresponding to the x and y
coordinates. All data are in vector form.
I would like to ext...

duplicate data points: need to set 'duplicate = ..'
Unfortunately there seems no help screen on "duplicate". I'd prefer
