[R] Using multiple dat files

[Sibylle Stöckli]

Dear community

To import multiple .dat  weather files I am using list.files().
I intend to use the R package “ClimInd” to calculate different agroclimatic indicators. 

Question: Is there another solution to import multiple .dat files so that I can select elements from the list, e.g. one specific weather file (example AAR_DailyWeather)?
 
 
# Import multiple .dat files weather data
filelist <- list.files(path = "O:/Data-Work/……./Daten_RA-MeteoCH_1990-2021", pattern='*.dat', all.files= T, full.names= T)
W <- lapply(filelist, function(x) read.table(x, header = TRUE, sep = "", colClasses = "numeric", comment.char = ""))
W[[1]]
 
> dd(data = W[[1]]$Precip, time.scale = W[[1]]$year)
Fehler in W[[1]]$year : $ operator is invalid for atomic vectors
 
Kind regards
