如何实现ABCDEFG之间的相互比较？

Question

例如，A和B，A和C ... A和G？那么B＆C，B＆D ... B＆G？ ...然后，E＆F，E＆G，F＆G？我的代码如下。

library(basicTrendline) 
x<-RL$A 
y<-RL$B
trendline(x,y,model="line3P",ePos.x = "topleft",
             linecolor = "black",CI.color = NA, eDigit=2, 
             xlab=c("Abiomass(g)"), ylab=c("Bbiomass(g)"), text.col="red")

Answer 1

pairs(RL, panel = panel.smooth)
