Dear community I have started to use the foreSIGHT package fo calculate some climatic indicators. Example library(foreSIGHT) func_avgDSD(WAAR$Ta, attArgs) Dataset (WAAR, Ta = average daily temperature) Year DOY Ta 1990 1 -2.45 1990 2 1.54 . . 2001 1 4.54 , 2001 205 15.65 2001 206 20.14 . 2001 365 8.65 .. 2023 1 0.45 Questions: Is it possible to run the foreSIGHT with DOY numbers not dates (e.g. 1983-04-09 23.64) and additionally separate years? I have some problems to understand attArgs. Up to now I have not found any reference. How do I need to prepare the list? And where I can set the threshold? Sometimes there are indicators without any definition of the threshold? E.g. cold seasons length: func_CSL (data) how is a cold day defined here (the threshold for cold days), there is no attArgs?
