Description

Returns the data set with following columns added:

Usage

calc_sequential_difference(data, values, arrange, ...,
  rel_diff_signif = 0.2, rise_above = 0, fall_below = 0)

Arguments

data	A tibble.
values	The column with the values to calculate the difference with.
arrange	The column to arrange the data by.
...	The columns to group by.
rel_diff_signif	A relative difference above this cut-off is considered significant.
rise_above	A rise above this cut-off is required before it is considered significant.
fall_below	A fall below this cut-off is required before it is considered significant.

Details

• COLUMN_diff: The difference to the row before.

• COLUMN_diff_rel: The difference to the row before as relative difference of the row before. Either positive or negative.

• COLUMN_diff_signif: Is the relative difference >= rel_diff_signif.

• COLUMN_diff_cat: "rise", "fall" or "insignificant"

• COLUMN_diff_risen: TRUE if "rise" at least once per group.

• COLUMN_diff_rise_max: The maximal increase per group.

• COLUMN_diff_rise_rel_max: The maximal relative increase per group.

• COLUMN_diff_rise_first: The first rise.

• COLUMN_diff_rise_first_seq: The first rise ignoring rows with COLUMN_diff_in_seq == FALSE.

• COLUMN_diff_diff_rise_signif_above: TRUE if a rise was at least >= rise_above or if the previous value was >= rise_above an increase of >= rel_diff_signif.

• COLUMN_diff_rise_signif_above_first: The first rise in COLUMN_diff_rise_signif_above_first per group.

• COLUMN_diff_risen_signif_above: TRUE if there was at least one per group with COLUMN_diff_rise_signif_above == TRUE.

• COLUMN_diff_fallen: TRUE if "fall" at least once per group.

• COLUMN_diff_fall_max: The maximal decrease per group.

• COLUMN_diff_fall_rel_max: The maximal relative decrease per group

• COLUMN_diff_fall_first: The first decrease.

• COLUMN_diff_fall_first_seq: The first decrease ignoring rows with COLUMN_diff_in_seq == FALSE.

• COLUMN_diff_diff_fall_signif_below: TRUE if a fall was at least <= fall_below or if the previous value was <= fall_below an increase of <= rel_diff_signif.

• COLUMN_diff_fall_signif_below_first: The first fall in COLUMN_diff_fall_signif_below_first per group.

• COLUMN_diff_falln_signif_below: TRUE if there was at least one per group with COLUMN_diff_fall_signif_below == TRUE.

• COLUMN_diff_max: The maximal increase or decrease per group.

• COLUMN_diff_rel_max: The maximal relative increase or decrease per group.

• COLUMN_diff_in_seq: Is this row the next in sequqnece or was >= 1 skipped?

Value

A tibble.
