次のように、ヒストグラムと累積ヒストグラムに密度曲線を追加したいと思います。
これが私が行くことができる限りです:
hist.cum <- function(x, plot=TRUE, ...){
h <- hist(x, plot=FALSE, ...)
h$counts <- cumsum(h$counts)
h$density <- cumsum(h$density)
h$itensities <- cumsum(h$itensities)
if(plot)
plot(h)
h
}
x <- rnorm(100, 15, 5)
hist.cum(x)
hist(x, add=TRUE, col="lightseagreen")
#
lines (density(x), add = TRUE, col="red")
説明なしで提供:
## Make some sample data
x <- sample(0:30, 200, replace=T, prob=15 - abs(15 - 0:30))
## Calculate and plot the two histograms
hcum <- h <- hist(x, plot=FALSE)
hcum$counts <- cumsum(hcum$counts)
plot(hcum, main="")
plot(h, add=T, col="grey")
## Plot the density and cumulative density
d <- density(x)
lines(x = d$x, y = d$y * length(x) * diff(h$breaks)[1], lwd = 2)
lines(x = d$x, y = cumsum(d$y)/max(cumsum(d$y)) * length(x), lwd = 2)
