> Hello,

> "High Z Outlier", "Default","Exponential (used)")
>        } else {
>        leg.txt <- c("Data", "Statistical Outlier", "Spatial Outlier",
> "High Z Outlier", "Default (used)","Exponential")
> }
> legend("topleft", legend=leg.txt,
> col=c("black","yellow","red","orange","blue","black"), pch =
> c(16,16,16,16,1,1), cex=0.85 )
