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