Drawing Polygons with xyplot in lattice
...e plot at a time with the simple plot commmand (using polygon after having first drawn the line plot), but am having difficulty replicating it with xyplot.
Here is some sample code (with 4 countries and 10 years), which is as far as I've been able to get:
library(lattice)
df<-data.frame(c(u5cmr=round(runif(40)*100)),country=c(rep("Angola",10), rep("Benin",10), rep("Botswana",10), rep("Burkina Faso",10)), year=rep(1991:2000,4))
names(df)<-c("u5cmr", "country", "year")
xyplot(u5cmr ~ year | country , ylab = "U5 cm...
