I don't know what your data looks like, so this is hard. levelplot
assumes you have triplets (x,y,z), where x and y only take a few values,
and it plots the grid of those values using z to set the colour. In
your example you read x amd y from a file. So just round them to fewer
df$x <- round(df$x, -2) # round to -2 decimal places, i.e. to hundreds
df$y <- round(df$y, -2)
levelplot(z ~ x+y, data=df)
