Abstract
This process creates aggregations based on the previously stratified data for qualifications. It includes statistics based on the responses given to the qualification-related fields on the Europass survey.# http://rmarkdown.rstudio.com/html_document_format.htm
sourceTimeNeeded <- c(0);
source.starting.time <- proc.time()[3]Information about the libraries, environment, sources used and their execution is reported. Aditional information is provided within section tabs. Navigating through the report is also possible through the table of contents. Tables reported, can be dynamically filtered, searched ordered and exported into various formats.
