tbr_gmean: Time-Based Rolling Geometric Mean

In tbrf: Time-Based Rolling Functions

Time-Based Rolling Geometric Mean

Description

Produces a a rolling time-window based vector of geometric means and confidence intervals.

Usage

tbr_gmean(.tbl, x, tcolumn, unit = "years", n, ...)

Arguments

.tbl	a data frame with at least two variables; time column formatted as date, date/time and value column.
x	column containing the values to calculate the geometric mean.
tcolumn	formatted time column.
unit	character, one of "years", "months", "weeks", "days", "hours", "minutes", "seconds"
n	numeric, describing the length of the time window.
...	additional arguments passed to gm_mean_ci

Value

tibble with columns for the rolling geometric mean and upper and lower confidence levels.

Examples

## Return a tibble with new rolling geometric mean column
tbr_gmean(Dissolved_Oxygen, x = Average_DO, tcolumn = Date, unit = "years", n = 5)

## Not run: 
## Return a tibble with rolling geometric mean and 95% CI
tbr_gmean(Dissolved_Oxygen, x = Average_DO, tcolumn = Date, unit = "years", n = 5, conf = .95)
## End(Not run)
