Well, as you did not provided some data
mat<-cbind(sample(1:5, 70, replace=T), sample(1:5, 70, replace=T),
rnorm(70))
dim(mat)
[1] 70 3
library(akima)
filled.contour(interp(mat[,1], mat[,2], mat[,3], duplicate="mean"))
image(interp(mat[,1], mat[,2], mat[,3], duplicate="mean"))
is this what you want?
