template_DRAC: Create a DRAC input data template (v1.2)

In R-Lum/Luminescence: Comprehensive Luminescence Dating Data Analysis

Create a DRAC input data template (v1.2)

Description

This function returns a DRAC input template (v1.2) to be used in conjunction with the use_DRAC function

Usage

template_DRAC(nrow = 1L, preset = NULL, file_input = NULL, notification = TRUE)

Arguments

nrow	integer (with default): specifies the number of rows of the template (i.e., the number of data sets you want to submit).
preset	character (optional): By default, all values of the template are set to NA, which means that the user needs to fill in all data first before submitting to DRAC using use_DRAC(). To reduce the number of values that need to be provided, preset can be used to create a template with at least a minimum of reasonable preset values. preset can be one of the following: quartz_coarse quartz_fine feldspar_coarse polymineral_fine DRAC-example_quartz DRAC-example_feldspar DRAC-example_polymineral Note that the last three options can be used to produce a template with values directly taken from the official DRAC input .csv file.
file_input	character file connection to a DRAC .csv file, the file will be imported and translated to the template that can be used by use_DRAC. Please note that there is not check on validity of the .csv file.
notification	logical (with default): show or hide the notification

Value

A list of class DRAC.list.

Function version

0.1.1
