In trendseries: Extract Trends from Time Series

daily and weekly trends reject explicitly missing interior values

Code
  augment_trends(data, methods = "ma", window = 3, frequency = frequency, .quiet = TRUE)
Condition
  Error in `.check_regular_grid()`:
  ! Series has 1 interior observation with missing values.
  x Missing: "2020-01-05"
  i Impute interior missing values before extracting trends or decomposing the series.

Code
  decompose_series(data, methods = "regression", frequency = frequency, .quiet = TRUE)
