我在链接中看到了一个非常有趣的三元图模板，由 Nicholas Hamilton 制作：

Ternary plot and filled contour

代码如下：

#Orignal Data as per Question

library(ggplot2)
library(ggtern)

a <- c(0.1,0.5,0.6,0.2,0.004166667,0.45) 
b <- c(0.75,0.1,0.951612903,0.918103448,0.7875,0.45)
c <- c(0.15,0.3,0.048387097,0.081896552,0.208333333,0.10) 
d <- c(500,2324.90,2551.44,1244.50,551.22,-644.20,-377.17,-100,2493.04) 
df <- data.frame(a,b,c,d)

#For labelling each point.
df$id <- 1:nrow(df)

#Build Plot
ggtern(data=df,aes(x=c,y=a,z=b),aes(x,y,z)) + 
  stat_density2d(geom="polygon",n=400,aes(fill=..level..,weight=d,alpha=abs(..level..)),binwidth=100) + 
  geom_density2d(aes(weight=d,color=..level..),binwidth=100) +
  geom_point(aes(fill=d),color="black",size=5,shape=21) + 
  geom_text(aes(label=id),size=3) + 
  scale_fill_gradient(low="yellow",high="red") + 
  scale_color_gradient(low="yellow",high="red") + 
  theme_tern_rgbw() + 
  theme(legend.justification=c(0,1),legend.position=c(0,1)) + 
  guides(fill = guide_colorbar(order=1),alpha= guide_legend(order=2),color="none") + 
  labs(  title= "Ternary Plot and Filled Contour",fill = "Value,V",alpha="|V - 0|")

问题是随着这个包的更新，出现了一些错误：

Warning messages:
1: Ignoring unknown aesthetics: weight 
2: Ignoring unknown aesthetics: weight 
3: Removing Layer 1 ('StatDensity2d'),as it is not an approved stat (for ternary plots) under the present ggtern package. 
4: Removing Layer 2 ('GeomDensity2d'),as it is not an approved geometry (for ternary plots) under the present ggtern package.

问题是不再支持 geom_density2d 和 stat_density2d，而是由 geom_density_tern 和 stat_density_tern 代替。包的修改是非常大的，在这一点上，即使是更换它，任何新的错误都会发生。包的语法发生了很大的变化。有人知道如何翻译这段代码并使其适用于新版本吗？

我感兴趣的输出是这样的：

有人可以帮我吗？

预先感谢您对最终的支持！
