我正在尝试在 R 中绘制板布局热图。板布局只是 8(行)x 12(列)圆(井)。行用字母标记,列用数字标记。每个孔需要填充一些颜色强度取决于定性或定量变量。盘子布局是这样的:
这是小数据集:
set.seed (123)
platelay <- data.frame (rown = rep (letters[1:8], 12), coln = rep (1:12, each = 8),
colorvar = rnorm (96, 0.3, 0.2))
rown coln colorvar

有没有可以轻松做到的包?是否可以在 base 或 ggplot2 或其他可以实现此目标的包中编写函数。
