[R] Maps and plotting

At our facility we have multiple sample points that are sampled on any given day. What I would like to do is create a map of the facility with the sample points (and point labels) and when we have out of specification results, place a transparent dot over the area on the map. As the number of OOS

You can return a list of them all root <- function(var) { return(list(test1 = PP.test(var, lshort = T), test2 = ...)) } output <- root(var) Then you can print them, save them, or whatever. Or you could just print them out in the function root <- function(var) { #---Phillips

Only the last appears, because the function returns only the last, which then gets printed. The answer to your question depends on whether you want to see the results or store them. To see them, try the following: root.print <- function(var) { #---Phillips-Perron print(PP.test(var,

I would return the values from the various tests in a list. If you only want them to print and not for use in other parts of your program you could explicitly print each test using print(). root <- function(var) { #---Phillips-Perron test1 <- PP.test(var, lshort = TRUE) test2 <- PP.test(var, ls
