ihs(x)

`x`	a numeric or complex vector.

A numeric vector of transformed values.

x <- 1:1e4

plot(ihs(x), pch = 20, cex = 0.2, col = "red")
points(log(x), pch = 20, cex = 0.1, col = "black")

x <- rnorm(1e5, mean = 0, sd = 100) ^ 2
plot(density(x))

plot(density(ihs(x)))
lines(density(log1p(x)), col = "blue")
lines(density(log(x)), col = "red")
