FindMinima: Find Local Minima

In patrickreidy/ag501: Carstens AG501 Electromagnetic Articulograph

Description

Find the local minima within one or more channels of kinematic data.

Usage

FindMinima(x, ...)

## S3 method for class 'data.frame'
FindMinima(x, channels = NULL, matches = NULL,
  from = -Inf, to = Inf, ...)

## S3 method for class 'list'
FindMinima(x, channels = NULL, matches = NULL, from = -Inf,
  to = Inf, ...)

Arguments

x	A data.frame (or a list of data.frames) that contain(s) kinematic data (e.g., position, velocity, speed, or acceleration data). x must have one column named Time and at least one other column.
...	Placeholder for future methods.
channels	A character vector, each element of which should match exactly the name of some column in x other than Time. Default matches all columns of x other than Time.
matches	A pattern used to match columns in x. A non-null value for this argument will supercede a non-null value for the channels argument. Default matches all columns of x other than Time.
from, to	Atomic numerics. Local maxima will only be found within the [from,to] interval. Default values will include all available data in the channel.

Value

A data table with the following variables:

• Channel: the name of the channel in which the local maximum occurs.

• Time: the time at which the local occurs.

• Value: the amplitude value of the local minimum.
