Dear All
I want to convert a scatter plot to a continuous contour plot. I have "x" as a variable
and "y" as another variable.
is there any package for this?
can anybody halp me?
A contour plot of values associated with the points, or a contour plot
of the density of the points? For the former, I think you want to use
the akima package; for the density estimate, you could use kde2d from
the MASS package.
In either case, you need to compute the values of the function on a
grid, then the contour() function can plot it.
