Next, we are going to see the how I tried using simply spread

First, I charged the two libraries that I will be using

CalendarPlot of the contaminant NOX

CalendarPlot of the contaminant NO

CalendarPlot of the contaminant PM10

CalendarPlot of the contaminant O3

CalendarPlot of the contaminant SO2

CalendarPlot of the contaminant CO

CalendarPlot of the contaminant NO2

TimeVariation of the contaminant NOX

TimeVariation of the contaminant NO

TimeVariation of the contaminant PM10

TimeVariation of the contaminant O3

TimeVariation of the contaminant SO2

TimeVariation of the contaminant CO

TimeVariation of the contaminant NO2

So that's my R project, I have some issiues with the libraries because the most part weren't working properly, so I have to search for my own

I Hope you liked my project
