如何在 ggplot2 中绘制密度而不是线？

如何解决如何在 ggplot2 中绘制密度而不是线？

如何让 ggplot2::stat_function 生成密度图而不是 geom = "line"？

My_table$distances 是数字

mixmdl <- mixtools::normalmixEM(My_table2$distances,k = 4)

plot_GMM(mixmdl,4)
mixmdl$posterior
x <- mixmdl$x
x <- data.frame(x)

GMMplot <- ggplot2::ggplot(data.frame(x)) +
  ggplot2::geom_density(ggplot2::aes(x),color="black",alpha = .2) +
  ggplot2::stat_function(geom = "line",fun = plot_mix_comps,args = list(mixmdl$mu[1],mixmdl$sigma[1],lam = mixmdl$lambda[1]),colour = "blue1",alpha = 1.5) +
  xlab("distance (nm)")+theme_bw()+
  theme(axis.title.y=element_blank(),axis.text.y=element_blank(),axis.ticks.y=element_blank(),legend.position = "none")+
  ggplot2::stat_function(geom = "line",args = list(mixmdl$mu[2],mixmdl$sigma[2],lam = mixmdl$lambda[2]),colour = "blue2")+
  ggplot2::stat_function(geom = "line",args = list(mixmdl$mu[3],mixmdl$sigma[3],lam = mixmdl$lambda[3]),colour = "blue3")+
  ggplot2::stat_function(geom = "line",args = list(mixmdl$mu[4],mixmdl$sigma[4],lam = mixmdl$lambda[4]),colour = "blue4")+ylim(0.00,0.043)
GMMplot
