local.min.max: Local minimum and maximum

Description

Calculates the local minimums and maximums in a numeric vector, indicating inflection points in the distribution.

Usage

local.min.max(x, dev = mean, plot = TRUE, add.points = FALSE, ...)

Arguments

x

A numeric vector

dev

Deviation statistic (mean or median)

plot

plot the minimum and maximum values with the distribution (TRUE/FALSE)

add.points

Should all points of x be added to plot (TRUE/FALSE)

...

Arguments passed to plot

Value

A list object with:minima minimum local values of xmaxima maximum local values of xmindev Absolute deviation of minimum from specified deviation statistic (dev argument)maxdev Absolute deviation of maximum from specified deviation statistic (dev argument)

Examples

                                                 
x <- rnorm(100,mean=1500,sd=800) 
( lmm <- local.min.max(x, dev=mean, add.points=TRUE, main="Local Minima and Maxima") )

# return only local minimum values
   local.min.max(x)$minima
