用户,我想有一些三元图("vcd")的提示.

我有这个数据帧:

a <- c(0.1, 0.5, 0.5, 0.6, 0.2, 0, 0, 0.004166667, 0.45) 
b <- c(0.75,0.5,0,0.1,0.2,0.951612903,0.918103448,0.7875,0.45)
c <- c(0.15,0,0.5,0.3,0.6,0.048387097,0.081896552,0.208333333,0.1) 
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)

而我正在建立一个三元图:

ternaryplot(df[,1:3], df$d)

如何映射连续变量d,获得与此类似的结果？

R-用户,

我有这个数据帧:

head(Niger_Meteo_98.11)
  X.ID_punto    MM.GG.AA T2m_max  
1          1    01/01/98 303.235 
2          2    01/01/99 303.356 
3          3    01/01/00 303.477 
4          4    01/01/01 303.604 
5          5    01/01/02 303.759 
6          6    01/01/03 303.915 

我只需要从2002年获得值.所以,我应该在列上选择MM.GG.AA那些以" /02" 结尾的行.我没有在网上找到任何东西......任何提示？谢谢!
