ggplot2 for procrustes rotation in vegan
ggplot2 for procrustes rotation in vegan
我想绘制素食主义者使用 ggplot2 获得的 RDA 对象之间的 procrustes 旋转。
library(vegan)
#perform two RDAs, do procrustes:
pro.test <- procrustes(rda.t1,rda.t2)
我从 class "procrustes" 的列表中提取了 x,y 坐标并添加了一个因子 "dates"。
test <- data.frame(rda1=pro.test$Yrot[,1], rda2=pro.test$Yrot[,2])
test$dates <- c(rep("A", 8), rep("B",8), rep("C", 8))
test.2 <- data.frame(rda1=pro.test$X[,1], rda2=pro.test$X[,2])
test.2$dates <- c(rep("A", 8), rep("B",8), rep("C", 8))
现在基本剧情：
ggplot() +
geom_point(data=test, aes(x=rda1, y=rda2, color=dates)) +
geom_point(data=test.2,aes(x=rda1, y=rda2, color=dates))
我不能做的部分是在测试和测试中的每个对应点之间绘制细线。2
Vegan 确实用箭头而不是连接点来绘制这些旋转。然而，素食主义者不知道如何根据采样 groups/factors 来着色，这对我来说很重要。
在 ggplot 中有箭头会非常棒 - 我知道有一个 geom_segment 和参数 "arrow".
你能帮帮我吗？
