# Instructions to generate plots

Open a terminal and move into this folder.
Then, by simply typing "make", the plotter.R script will be run and all
generated plots will be put in "out/" folder.

# Datasets contained in this folder

1) "complete-results-survey357528.csv"
    Full dump of all responses taken from LimeSurvey
2) "selected-results.csv":
    Dataset containing only responses to questions which allow a quantitative analysis.
    For instance, compared to the full dump dataset, open-questions with free-text answers are not included.
3) "catordQUCODANSFULL_process.csv": 
    A dataset concerning only ordinal data (https://en.wikipedia.org/wiki/Ordinal_data).

# Other

- "plotter.R"
    This is the R script which, based on the content of datasets 2 and 3, generate all histograms and correlation maps.
    Output of the script are placed in the automatically generated "out" folder.
- "table.tex" and "table.pdf"
    Look here to understand how, in dataset 3, some responses have been mapped to numbers to allow correlation analysis.

The "out" folder contains all plots. Type "make clean" in a terminal to delete all generated contents; 
type again "make" to run the R script once more and refresh plots. 
Change plotter.R to modify data plotting properties or to run additional analysis.
