您能否看一下这段代码，让我知道如何重新排列级别以从蔗糖、p:c、p:c+u、p:c:l+u 开始？还要让传说从对照组开始？

这是我的代码：

    Nutrient <- as.factor(c("s", "p:c", "p:c+u", "p:c:l+u"))
    Nutrientlevels<-c("s", "p:c", "p:c+u", "p:c:l+u")
    levels(Nutrient) <- Nutrientlevels
    ggplot(df,aes(x = Nutrient, y = Consumption),levels)+
    geom_bar(aes(fill = Diet), stat = "identity",position = "dodge")+
    scale_fill_brewer(palette="Set3")+
    levels(Nutrient)+
    xlab("Nutrient")+
    ylab("Average consumption (mg)")+
    ggtitle("Average daily consumption")+
    theme(panel.grid.major = element_blank(), panel.grid.minor = 
    element_blank(),panel.background = element_blank(), axis.line = 
    element_line(colour = "black"))+
    guides(color=guide_legend(override.aes=list(fill=NA)))+
    theme_bw() +
    theme(panel.border = element_blank(), panel.grid.major = 
    element_blank(),panel.grid.minor = element_blank(), 
    axis.line = element_line(colour="black"))+
    theme(plot.title = element_text(hjust = 0.5))

非常感谢

也许这会起作用？

营养水平<- 有序（“s”、“p:c”、“p:c+u”、“p:c:l+u”）
