在生物学中,我们经常想要绘制剂量反应曲线.R包'drc'非常有用,基本图形可以轻松处理'drm models'.但是,我想将我的drm曲线添加到ggplot2中.
我的数据集:
library("drc")
library("reshape2")
library("ggplot2")
demo=structure(list(X = c(0, 1e-08, 3e-08, 1e-07, 3e-07, 1e-06, 3e-06,
1e-05, 3e-05, 1e-04, 3e-04), Y1 = c(0, 1, 12, 19, 28, 32, 35,
39, NA, 39, NA), Y2 = c(0, 0, 10, 18, 30, 35, 41, 43, NA, 43,
NA), Y3 = c(0, 4, 15, 22, 28, 35, 38, 44, NA, 44, NA)), .Names = c("X",
"Y1", "Y2", "Y3"), class = "data.frame", row.names = c(NA, -11L
))
使用基本图形:
plot(drm(data = reshape2::melt(demo,id.vars = "X"),value~X,fct=LL.4(),na.action = na.omit),type="bars") …
