[R] Colour area under density curve

Hello, I have this code to plot a certain normal distribution and represent the pnorm value for a certain x: x-300 xx - seq(2.5,7.5, by=0.1) yy - dnorm(xx,5.01,0.77) d-signif(pnorm(log(x), 5.01,0.77),4) xpts - round(exp(0:8)) par(bg = antiquewhite) plot(xx,yy, type=l, col=blue, lwd=2, xaxt=n,

[R] rcauchy density distribution

Hello, I'm taking samples from certain distributions and drawing a density distribution over the histogram of the samples It works fine for the chi-square and for the normal, but not for the cauchy. Any idea what I'm doing wrong? Thanks x - rchisq(1, df = 4) hist(x, freq = FALSE,
