R vous permet d’ajouter du texte \u00e0 vos graphique en utilisant la fonction text. Il vous suffit de fournir les coordonn\u00e9es du point o\u00f9 le texte doit \u00eatre affich\u00e9. Si vous n’en avez aucune id\u00e9e n’h\u00e9sitez pas \u00e0 utiliser la fonction locator() pour vous rep\u00e9rer.
Un exemple:<\/p>\n
host<-function(t){5\/(1+1000*exp(-1.18*t^0.4))}
time<-c(0:200)
par(mar=c(4, 6, 2, 1),cex.lab=1.3,cex.axis=1.2)
plot(host(time)~time,type='l',lwd=4.5,col=\"grey\",ylab=\"Plant radius (cm)\",
