Question

I would like to have a plot in R similar to the 2D smoothScatter plot, but with an extra dimension using something like a palette of different colours or a surface. Is this possible with any package?

Example:

x = rnorm(1000)
y = rnorm(1000,10)
z = rnorm(1000,5)
smoothScatter(x,y)

somemagicmethod(x,y,z)

Answer 1

library(fields)
library(akima)

s <- interp(x,y,z)
image.plot(s)
