Nous discutons la construction d un diagramme quantile quantile et d un diagramme de probabilité à l échelle normale avec r. By andrie de vries joris meys. We will be plotting q q plot with qqnorm function in r.
0 and 100 are the min and.
So we are good with syntax and let s apply the quantile function to the given data and let s see how it works.
