如何将plot理论帕累托分布在R？

Question

I need to plot theoretical Pareto distribution in R.

I want this as a line - not points and not polylines.

My distribution function is 1−(1/x)^2.

I plotted empirical distribution of my sample and also theoretical distribution at one graph:

ecdf(b2)
plot(ecdf(b2))
lines(x, (1-(1/x)^2), col = "red", lwd = 2, xlab = "", ylab = "")

But I got:

You can see that red line is not continuous, it's something like polyline. Is it possible to get the continuous red line?

Do you have any advices?

Answer 1

Use curve() instead.

library(EnvStats)
set.seed(8675309)
# You did not supply the contents of b2 so I generated some
b2 <- rpareto(100, 1, 2)
plot(ecdf(b2))
ppareto <- function(x) 1−(1/x)^2
curve(ppareto, col = "red", add = TRUE)
