Make a Time Enhanced Tibble — ts_signature

Returns a tibble that adds the time series signature from the timetk::tk_augment_timeseries_signature() function. All added from a chosen date column defined by the .date_col parameter.

Usage

ts_signature_tbl(.data, .date_col, .pad_time = TRUE, ...)

Arguments

.data: The data that is being analyzed.
.date_col: The column that holds the date.
.pad_time: Boolean TRUE/FALSE. If TRUE then the timetk::pad_by_time() function is called and used on the data.frame before the modification. The default is TRUE.
...: Grouping variables to be used by dplyr::group_by() before using timetk::pad_by_time()

Value

A tibble

Details
