r ggplot2 density-plot 我试图在7个不同的地理点上绘制3个变量的密度图,但输出并没有如预期那样显示。N在中间应该更高,但另一个似乎在不真实时绘制相同的模式,为什么?我该怎么修? Variable1 <- c(rep("E",7), rep("N",7),rep("L",7)) Variable2 <- c(rep(1:7, 3)) value <- c(12.44035...
A density plot is a representation of the distribution of a numeric variable. It is a smoothed version of the histogram and is used in the same kind of situation. Here is a basic example built with the ggplot2 library. Density Section Density theory Density plots are built in ggplot2 ...
