Specify thresholds for detecting start/end of season — set

Creates a data frame with threshold values for both increasing ("up") and decreasing ("down") trends. These values are used to detect threshold-crossing events in the time series that indicate the start/end of season.

Usage

set_thresholds(
  thres_up = round(seq(from = 0, to = 1, by = 0.1), 1),
  thres_down = round(seq(from = 1, to = 0, by = -0.1), 1)
)

Arguments

thres_up: Numeric vector. Threshold values for increasing trends (default: seq(from = 0, to = 1, by = 0.1) |> round(1)).
thres_down: Numeric vector. Threshold values for decreasing trends (default: seq(from = 1, to = 0, by = -0.1) |> round(1)).

Value

A data frame with two columns:

direction: A character vector indicating "up" for increasing trends or "down" for decreasing trends.
threshold: A numeric vector containing threshold values between 0 and 1.

Examples

# Get default thresholds (for increasing and decreasing trends)
default_thres <- set_thresholds()

# Get thresholds with custom rule
custom_thres <- set_thresholds(thres_up = c(0.3, 0.5), thres_down = NULL)
