In Mender: Visualizing Topological Loops and Voids

Function to extract the right tail of a histogram for display purposes.

Description

Sometimes, the most interesting part of a histogram lies in the tail, where details are obscured because of the scale of earlier peaks in the distribution. This function uses a user-defined target cutoff to extract the right tail of a histogram, preserving its structure as a histogram object.

Usage

tailHisto(H, target)

Arguments

H	A histogram object.
target	A real number; the target cutoff defining the portion of the tail of the histogram to be extracted.

Details

There is nothing special going on. The only sanity check is to ensure that the target is small enough that there is actually a part of the histogram that can be extracted. After that, we simply cut out the approprioate pieces, make sure they are structured properly, and return them.

Value

Returns another histogram object that only contains the portion of the histogram beyond the target cutoff.

Examples

set.seed(12345)
fakeData <- rexp(2000, rate = 10)
H <- hist(fakeData, breaks = 123, plot = FALSE)
H2 <- tailHisto(H, 0.3)
opar <- par(mai=c(0.9, 0.9, 0.6, 0.2))
plot(H, freq = FALSE)
par(mai=c(3.4, 3.0, 0.6, 0.6), new=TRUE)
plot(H2, freq = FALSE, main = "", col = "skyblue")
par(opar)
