Actually, my data is on a grid. The values are something like 0 < x < y <
0.05, with a 0.00005 step for both x and y. I tried using interp() as

data <- ..

x <- data$X

y <- data$Y

z <- data$Z

temp <- interp(x, y, z)

image(temp, add=TRUE)

I figured showing an image would just verify that the grid was formed
correctly, but that didn't seem to work.
