[R] plot xyz data in 2D

Dear Jacob,

Do you want something like this? Using dummy data instead of yours.
Copy-paste the output of dput() if you want to pass your data in a
format that is easy to use.

library(ggplot2)
dataset <- expand.grid(X = -3:3, Depth = seq(0, -1, by = -0.25))
dataset$Resistivity <- rnorm(nrow(dataset), mean = 1)
ggplot(dataset, aes(x = X, y = Depth, fill = Resistivity)) + geom_tile()

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
~ John Tukey
