在ggplot 2中在各個(gè)方面注釋我想用以下代碼對(duì)情節(jié)的最后一個(gè)方面進(jìn)行注釋：library(ggplot2)p <- ggplot(mtcars, aes(mpg, wt)) + geom_point()p <- p + facet_grid(. ~ cyl)p <- p + annotate("text", label = "Test", size = 4, x = 15, y = 5)print(p)但這段代碼在每個(gè)方面都對(duì)文本進(jìn)行了注釋。如果你能指導(dǎo)我如何只從一個(gè)方面得到注釋的文本，我將不勝感激。提前謝謝。

cyl = factor(8,levels = c("4","6","8")))p + geom_text(data = ann_text,label = "Text")
