[R-sig-Geo] Add text INSIDE spplot map

[Jose Iparraguirre]

Thanks Tom,

Here's an example using the usual dataset, meuse.

> data(meuse)
> coordinates(meuse) = ~x+y
> l1 = list("sp.text", c(179050, 330877),"Hola",col="red",font=2)
> spplot(meuse, c("ffreq"), sp.layout=list(l1), col.regions= "black", 
+ pch=c(19), key.space=list(x=0.1,y=.95,corner=c(0,1)))

Here, "Hola" is printed 'within the cloud', and it's not very legible -imagine thousands of additional points. I forgot to mention that I'd experimented with first=F/T, and the only change is that with first=TRUE, of course, the text 'Hola' is not printed. 
So, let me change the request of advice slightly: can I put such a text in such coordinates within a box, filling the box with a different colour, so that the text becomes more visible? (neither 'fill' nor 'bty' seem to work as elements of the list...).

Thanks in advance, and regards to everyone!

José

Hi,

first guess: did you try to add 'first=FALSE' to sp.layout (see ?spplot)?

For me it's not clear what means "outside the points" and "within the cloud of points". Maybe a 
reproducible example would clarify, though.
