Directional Movement Index

The directional_movement_index() is a generic S3 function that builds upon 'type-safe'-esque workflows limited to classes in in base R, and the package-wide dependencies. Ie. class in, class out. Each method is a soft wrapper of model.frame and therefore the OHLC-V series must be coercible to a data.frame.

Usage

directional_movement_index(x, cols, n = 10, ...)

Arguments

x

An OHLC-V series that is coercible to data.frame.

cols

(formula). An optional 3 variable formula passed into model.frame. Internally uses ~high + low + close by default.

n

(integer). An integer of length 1.

...

Additional parameters passed into model.frame

Value

An object of same class and length of x:

DX

double
