Details

An "index.html" page will be created in the directory "results" which is the root entry page of the HTML pages. The displayed result for every tracked function consists of two HTML pages. The first page is an overview on how often every line of code was executed. Code lines not executed are highlighted red, executed lines are shown in green. The second page is a graph representation of the execution flow of the function. Each code line has a edge pointing to the next code line that is executed subsequently. Thus loops and jumps become clearly visible.

Examples

Run this code


##  example function
foo <- function(x){
   y <- 0
   for(i in 1:100)
   {
      y <- y + i
   }
   return(y)
}

##  the name track is necessary
track <- tracker()

##  initialize the tracker
track$init()

##  inspect the function
##  res is the result of foo
res <- inspect(foo(10), track = track)

##  get the tracking info
resTrack <- track$getTrackInfo()

##  create HTML pages
printHTML(resTrack, baseDir=tempdir())
