```{r setup, include=FALSE}

```

Ce fichier sert juste à faire les graphes résumés de l'échantillon suivant:
```{r sample}
sample<-c(14.0, 7.6, 11.2, 12.8, 12.5, 9.9, 14.9, 9.4, 16.9, 10.2, 14.9, 18.1, 7.3, 9.8, 10.9,12.2, 9.9, 2.9, 2.8, 15.4, 15.7, 9.7, 13.1, 13.2, 12.3, 11.7, 16.0, 12.4, 17.9, 12.2, 16.2, 18.7, 8.9, 11.9, 12.1, 14.6, 12.1, 4.7, 3.9, 16.9, 16.8, 11.3, 14.4, 15.7, 14.0, 13.6, 18.0, 13.6, 19.9, 13.7, 17.0, 20.5, 9.9, 12.5, 13.2, 16.1, 13.5, 6.3, 6.4, 17.6, 19.1, 12.8, 15.5, 16.3, 15.2, 14.6, 19.1, 14.4, 21.4, 15.1, 19.6, 21.7, 11.3, 15.0, 14.3, 16.8, 14.0, 6.8, 8.2, 19.9, 20.4, 14.6, 16.4, 18.7, 16.8, 15.8, 20.4, 15.8, 22.4, 16.2, 20.3, 23.4, 12.1, 15.5, 15.4, 18.4, 15.7, 10.2, 8.9, 21.0)

```


```{r plot 1}
plot(1:length(sample)-1,sample,type="l",xlab="",ylab="",col="blue",lwd=2,ylim=c(0,25),xlim=c(0,100))
for (i in c(5,10,15,20))
{abline(h=i,lty="dotted",col=9)}
for (i in c(20, 40, 60, 80))
{abline(v=i,lty="dotted",col=9)}

```


```{r histogramme}
#truehist(sample,prob=FALSE,xlab="",ylab="",main="",xlim=c(0,25),ylim=c(0,25))
#temp<-hist(sample,freq=TRUE,xlab="",ylab="",main="",xlim=c(0,25),ylim=c(0,25),col="blue")
hist(sample,freq=TRUE,breaks=seq(min(sample),max(sample),length.out=11),xlab="",ylab="",main="",xlim=c(0,25),ylim=c(0,25),col="blue")
#barplot(temp$counts~I((temp$breaks[1:(length(temp$breaks)-1)]+temp$breaks[2:(length(temp$breaks))])/2),space=0,xlab="",ylab="",ylim=c(0,25),xlim=c(0,25))
for (i in c(5,10,15,20))
{abline(h=i,lty="dotted",col=9)}
for (i in c(5,10,15,20))
{abline(v=i,lty="dotted",col=9)}

#abline(v=0)
#abline(v=25)

#abline(h=0)
#abline(h=25)
```

Je n'arrive pas à reproduire exactement le graphe, je pense parce que je ne maîtrise pas assez ggplot.
