How can I add/display scale to two marginal plot?

RAD1998.all <- stack(list.ras)

list.files <- mixedsort(list.files(paste(getwd(), "/1998bil/", sep = ""), full.names = F, pattern = ".asc.bil")) 
#list.files

outlist <- substr(list.files, 31, 43)
#outlist

png(paste("1998",outlist[[1]],".png",sep=""))
levelplot(RAD1998.all[[1]])
dev.off()
  • I'm not convinced that this question is better asked here rather than at Stack Overflow (meta.gis.stackexchange.com/questions/1961/…) but if you think GIS SE, can you edit your question to provide some details about how you think this relates to GIS, please? Disclaimer: I do not work with R. – PolyGeo Aug 10 '14 at 23:48
  • It could be a non GIS question but I am looking for a solution from RasterVis and two marginal plot gives lots of raster information. I wish if scale is added either or both sides then it will be easy to quantify raster data. All I want is that is there anyway I can add scale ? – Nahm Aug 11 '14 at 0:05
  • More efficient to directly ask the author – user32309 Aug 11 '14 at 2:35
  • That's good idea. – Nahm Aug 11 '14 at 3:09
  • It is not yet implemented. I will try to find a solution. – Oscar Perpiñán Aug 17 '14 at 8:20

I have committed changes in the repository that implement the axis.

Use this code to install the latest development version:

## install.packages("devtools")
devtools::install_github("rastervis", "oscarperpinan")

Then, use the new argument axis.margin to enable the axis.

 f <- system.file("external/test.grd", package="raster")
 r <- raster(f)
 levelplot(r, axis.margin = TRUE)

  • My raster data is a NEXRAD rainfall data in inches per 5 min. Most of my raster cell values are less than 0.1"/5 min. – Nahm Aug 21 '14 at 17:14
  • First of all thanks a lot. It worked beautifully. I don't know how attach an image file at a "Add Comment". axis.margin worked fine with overlaying shape files demonstrated in your github, oscarperpinan.github.io/rastervis/FAQ.html#sec-7. It's so beautiful. Thanks, Nahm – Nahm Aug 21 '14 at 17:49
