X_min: Estimated minimum of a time series

In Rmfrac: Simulation and Statistical Analysis of Multifractional Processes

Estimated minimum of a time series

Description

This function computes the minimum of a time series for the provided time interval or its sub-interval.

Usage

X_min(X, subI = NULL, plot = FALSE, vline = FALSE, hline = FALSE)

Arguments

X	Data frame where the first column is a numeric time sequence t and the second the values of the time series X(t).
subI	Time sub-interval is a vector where the lower bound is the first element and upper bound is the second. Optional: If provided minimum of the sub-interval is returned, otherwise the whole time interval is considered.
plot	Logical: If TRUE, the time series, the minimum and corresponding t values are plotted in interactive sessions.
vline	Logical: If TRUE, a vertical line is plotted across the minimum.
hline	Logical: If TRUE, a horizontal line is plotted across the minimum.

Value

A list of numeric vector(s). The first element in the vector is the corresponding t value and second the minimum of the time series.

Examples

t <- seq(0, 1, length = 100)
TS <- data.frame("t" = t, "X(t)" = rnorm(100))
X_min(TS, subI = c(0.2, 0.8), plot = TRUE)
