Hi guys, I have a matrix with values varying from approximately -0.7 to 0.33 that I want to create a heatmap/levelplot with.
When I execute the levelplot function for my matrix, I end up getting colors that are adjusted to the max and min rather than around 0. In other words, ideally I would like to have a color ramp that goes from red (negative number), to white (0), to blue (positive); however, right now the value 0 is in the blue. Any insight on how to address this problem? Thanks in advance! example... my matrix "y" looks something like this A B C D E row1 -0.5046406 -0.021579587 -0.4419101 -0.2999195330 -0.4845047 row2 -0.3070091 -0.059065936 0.3329806 -0.0519335420 -0.5766368 row3 -0.7271707 0.073282855 -0.3181990 -0.2485017700 -0.5732781 row4 0.3329806 -0.017762750 -0.1513197 -0.1016354970 0.2528442 levelplot(y) yields a color scale from red (-0.8 to 0.2) to blue (0.2 to 0.4) I'd want the color scale to be from red (-0.8 to 0) to blue (0 to 0.4) ----- Lanna -- View this message in context: http://r.789695.n4.nabble.com/adjusting-levelplot-color-scale-to-data-tp3997342p3997342.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
