levelplot question
...have the value 3.5? I would have expected yellow, no? In my more complex example I wanted to create a heatmap (like yellow to red) up to a fixed threshold. All values above should get another color (like blue). Automatically, I generated both vectors like this: at <- c(vectorOfLowerValues, myThreshold, vectorOfHigherValues) col.regions <- c(vectorOfHeatmapColors, lastHeatmapColor, vectorOfColor"blue") But I get some values above the threshold which are not blue... Can anybody explain me why? (I've checked the length of both vectors and it's parts - this is correct - so &...
