Hey guys and gals, I searched through the forum and a bunch of R-mapping dedicated sites but have not found what i know is quite elementary process, mapping more than one layer on the same plot. I need to show some reference lines for the map to make sense. I know the below wont work for anyone but to show what im trying to do:
TazFile <- "data/input/TAZ.shp" UGBFile<- "data/input/metugb.shp" TazShape <- readShapeSpatial(TazFile) UGBShape <- readShapeSpatial(UGBFile) #Write out to pdf pdf("Results/HhEmpForecast.pdf", width=8.2, height=11, onefile=TRUE) #Households plot(TazShape, col=colsHh[findInterval(TazShape$Hh, brksHh, all.inside=TRUE)]) plot(UGBShape) title(main="Households Forecast by Taz") legend(4199277,860791.2,title="Total Households by Taz",LegBrksHh,fill=colsHh,cex=.8) #Employment plot(TazShape, col=colsEmp[findInterval(TazShape$Emp, brksEmp, all.inside=TRUE)]) title(main="Employment Forecast by Taz") legend(4199277,860791.2,title="Total Employment by Taz",LegBrksEmp,fill=colsEmp,cex=.8) #Close file dev.off() I need Households and employment on separate maps but i need the UGB file to be on each for reference. Doing it the above way obviously puts the reference map (UGB) on a separate map. So how do i plot them on the same page. I thought this was easy enough but im not finding a simple answer. Thanks for the help.
