Look up the col.regions argument. On 12/10/2022 16:44, rain1290--- via R-sig-Geo wrote:
I have climate data that I have plotted on a global map using a levelplot map. However, I am trying to adjust the default coloring scheme to allow for only blue and red shades to appear. Ideally, I am trying to showcase blue for the positive values, and red for the negative values, along with a whitish coloring near and at 0. The default coloring scheme isn't bad, but I think a blue-red-white coloring would allow the plot to appear more visually pleasing. Here is the code that I have now to create my current levelplot:#packages installed library(raster) library(ncdf4) library(maps) library(maptools) library(rasterVis) library(ggplot2) library(rgdal) library(sp) library(gridExtra) library(grid) library(RColorBrewer) #Using levelplot FPlot10 <- levelplot(FDifference5,margin=F,at=c(seq(-50,150,10)),pretty=TRUE, par.settings=mapTheme, main="Higher end") FM10 <- FPlot10 + latticeExtra::layer(sp.lines(world.outlines.sp)) This yields a range of nice default colors, but I'd like to adopt something with only shades of red and blue (with white at and around 0). I can do it easily in ggplot, but levelplot appears completely different in using color commands (if they exist). Is that even possible in levelplot? Thank you!
