persp function question
Hello,
I have a question about persp function:
I made my classical matrix with x, y and z variables and I dont know why I obtain a 3D image with overestimate heights.
Here is my script:
microtopo = read.csv2("topo2.csv", dec=".")
attach(microtopo)
require(akima) # for persp or
zz <-interp (x, y, z)
persp(zz)
See also my attach file
Thanks,
Best regards
JS
