If you cant get what you want from package code, and you know a bit about the KML format you are trying to produce, then try using the R 'brew' package, which lets your write a template which can have loops, variable substitutions, and other bits of R code in it. For example, here creating a simple set of KML points from a data frame called 'cpts': <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://earth.google.com/kml/2.1"> <Document> <% for(i in 1:nrow(cpts)){ %> <Placemark> <Name><%=paste("pt-",i,sep="")%></Name> <Point> <coordinates><%=cpts[i,]$Xt%>,<%=cpts[i,]$Yt%>,0</coordinates> </Point> </Placemark> <% } %> </Document> </kml> results in a KML with lots of these: <Placemark> <Name>pt-4</Name> <Point> <coordinates>-43.93769,-19.92065,0</coordinates> </Point> </Placemark> - its a lot easier than writing lots of cat() and other formatting nonsense in R code! But if you can get package code to do it, that's the way to go. But for outside-the-box solutions, install.packages("brew")!
