In the plot below, there are some grid cells that have values below 10, which
is the lowest "cut" value I have specified. Is there a way, without
adjusting the number of cuts, to tell R to fill in those cells with the
lowest possible color (in this case greeen)? There is a white "hole" in the
image about a quarter of the way in from the left side, this is what I would
like to correct. Thanks...Eric
The code:
pts<-list("sp.points",K.dat,pch=3,col="black")
cuts<-c(10,20,30,40,50,60,70,80,90,100,200,300,400,500,600,700,800,900,1000)
spplot(lzm.krige.dir["var1.pred"],at=cuts,colorkey=list(at=log10(cuts),at=log10(cuts),labels=as.character(cuts)),scales=list(draw=TRUE),
xlab="Easting",ylab="Northing",key.space="right",cex=1.1,col.regions=terrain.colors(30),main="Hydraulic
Conductivity of Layer 2",sp.layout=list(pts))

Hi Eric,
As far as I know you need to set the lower value of cuts to the minimum
of the dataset to prevent this white space from occuring. If you don't
want to see this in the colorbar, you need to adjust it using the
colorkey argument.
And a non-technical note, you e-mail doesn't give a lot of background
regarding your problem. spplot is a function that is only used by people
working with geographic data, which is probably a small subset of the
total community. See the posting guide for some hints about what kind of
information is necessary in an e-mail to r-help, for example a
reproducible example. In addition, there is a mailing list specifically
meant for geographic data, r-sig-geo, where you are more likely to get
the answers you are looking for.
cheers and good luck,
Paul
