use same breaks and colors, but the displayed scale are different-image.plot()
...data
x<- 1:10; y<- 1:10; z<- outer( x,y,"+");z2<- outer( x,y,"-")
#Quick view them
image.plot(x,y,z) #relatively larger value
image.plot(x,y,z2) #relatively small value
#define the same breaks and colors
brks<-quantile(c(as.vector(z),as.vector(z2)),na.rm=TRUE)
colsn<-length(brks)-1
cols<-gray((colsn:1)/colsn)
#I expect they use the same breaks and colors
par(mfrow=c(1,2))
image.plot(x,y,z,breaks=brks,col=cols)
image.plot(x,y,z2,breaks=brks,col=cols)
par(mfrow=c(1,1))
I think they really use the same breaks and colors, but you can see the
color legends...

Consulta spplot
...ible visualizar la leyenda
de cada una de las capas?
Actualmente solo visualizo la de la capa base, el mdt.
base<-spplot(mdt,col.regions=colMDT, at=pMDT,main=paste(idx[1]),
par.settings = list(panel.background=list(col="aquamarine")))
nubes<- spplot(n[[1]],col.regions=colsN, at=pN)
preci <- spplot(p[[1]],col.regions=colsP, at=pP)
png(paste("precipitacion.png",sep=""),width=600, height=600,bg="white")
print(base+nubes+preci)
dev.off()
Esto sería un ejemplo de lo que hago:
