In trendseries: Extract Trends from Time Series

mixed vector windows use the first window for other methods

Code
  mixed <- extract_trends(series, methods = c("ma", "wma"), window = c(3, 6),
  .quiet = TRUE)
Condition
  Warning:
  Multiple `window` values are only supported for "ma", "median", and "henderson" methods.
  i Using first value (3) for method(s) "wma".

mixed vector windows also reach the data-frame interface

Code
  mixed <- augment_trends(data, methods = c("ma", "wma"), window = c(3, 6),
  .quiet = TRUE)
Condition
  Warning:
  Multiple `window` values are only supported for "ma", "median", and "henderson" methods. i Using first value (3) for method(s) "wma".

invalid Kalman ratios and variances are rejected

Code
  extract_trends(series, methods = "kalman", smoothing = NA_real_, .quiet = TRUE)
Condition
  Error in `.kalman_smooth()`:
  ! Kalman `smoothing` must be one finite, positive noise ratio

Code
  extract_trends(series, methods = "kalman", smoothing = 0, .quiet = TRUE)
Condition
  Error in `.kalman_smooth()`:
  ! Kalman `smoothing` must be one finite, positive noise ratio

Code
  extract_trends(series, methods = "kalman", params = list(kalman_process_noise = -
    1), .quiet = TRUE)
Condition
  Error in `.kalman_smooth()`:
  ! Kalman "process_noise" must be one finite, non-negative variance
