Assign calendar years to tree-ring series in an rwl-style data frame

Source: R/trs_end_date.R
trs_end_date.Rd

Sets the row names (years) of an rwl-style data frame based on a specified end year. Optionally trims trailing rows with only NA values.

Usage

trs_end_date(x, end_year = 2025, trim = FALSE)

Arguments

x

A data.frame of class "rwl", with each column representing a tree-ring series.

end_year

An integer. The calendar year assigned to the most recent tree ring (last row).

trim

Logical. If TRUE, the data frame is trimmed to remove leading and trailing rows with no data (see trs_trim).

Value

A data.frame with row names set to calendar years.

Examples

rwl <- trs_pseudo_rwl(n_series = 2, series_length = 50)
trs_end_date(rwl, end_year = 2000)
