 Dear R People:

in the function loess, how can one add the weight of the points which is
contained in the variable "nbtotal"

Data :
Nbtotal P_alim H_eau


xyplot(P_alim ~ H_eau,
        auto.key = list(points = T, lines = F),data = data,
        type = c("p", "smooth"), span=.2,
  scales = "free", layout = c(1, 1),
        main="",
        xlab="Hauteur d'eau (en m)",
        ylab="taux d'alimentation")


the graph xyplot is not modified if the weights term is added
xyplot(P_alim ~ H_eau,
        auto.key = list(points = T, lines = F),data = data,
        type = c("p", "smooth"), span=.2,weights=Nb_total,
  scales = "free", layout = c(1, 1),
        main="",
        xlab="Hauteur d'eau (en m)",
        ylab="taux d'alimentation")


Thanks in advance,

Alain ponsero
