Usage

## S3 method for class 'tfm'
setinputs(
  mdl,
  xreg = NULL,
  inputs = NULL,
  y = NULL,
  envir = parent.frame(),
  ...
)

setinputs(mdl, ...)

## S3 method for class 'um'
setinputs(mdl, xreg = NULL, inputs = NULL, y = NULL, envir = NULL, ...)

Arguments

mdl	A um or tfm object.
xreg	Optional matrix of exogenous regressors.
inputs	Optional list of tf objects (only for tfm).
y	Optional ts object for output series.
envir	Environment for evaluation. Default is calling environment.
...	Additional arguments passed to model constructor.
