JDay_to_date: Transform JDay to date

In EduardoFernandezC/dormancyR: Functions to Compute Chill Metrics

Transform JDay to date

Description

In agricultural assessments, the begining and end for a period of interest (e.g. chill accumulation) are often expressed as Julian days (JDay) or Day Of the Year (DOY). However, this makes difficult the interpretation of the results since most people are used to see dates. This function transform JDays into dates

Usage

JDay_to_date(JDay, year, date_format = "%Y-%m-%d", na.rm = FALSE)

Arguments

JDay	is a numeric vector of length = 1 or longer containing integers between 1 and 366
year	is a numeric input to define the year for which the JDay is transformed to date
date_format	is a character vector representing the format in which the date should be retrieved. For more options see as.Date
na.rm	is a boolean parameter used to skip the missing values. Default is set to NULL to produce an error in case the JDay vector contains some

Examples

JDay_to_date(JDay = 67 : 69, year = 2020, date_format = "%d.%m.%Y")

JDay_to_date(JDay = c(67, NA, 69), year = 2025, date_format = "%d.%m.%Y",
             na.rm = TRUE)
