Description

These functions convert a fftab object to a specified representation:

• to_cplx(): Converts to complex representation (fx).

• to_rect(): Converts to rectangular representation (re, im).

• to_polr(): Converts to polar representation (mod, arg).

Usage

to_cplx(x, .keep = "unused")
to_rect(x, .keep = "unused")
to_polr(x, .keep = "unused")

Value

A modified fftab object containing the specified representation:

• to_cplx(): Adds the fx column for complex values.

• to_rect(): Adds the re and im columns for rectangular components.

• to_polr(): Adds the mod and arg columns for polar components.

Arguments

x

A fftab object.

.keep

Specifies which columns to retain. See dplyr::mutate().

Details

• to_cplx(): Converts from rectangular (re, im) or polar (mod, arg) components to complex form.

• to_rect(): Converts from complex (fx) or polar components to rectangular form.

• to_polr(): Converts from complex (fx) or rectangular components to polar form.
