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
Sibylle

Hello,
I find it strange that the error is complaining about the 2nd argument,
W[[1]]$year. It seems that column W[[1]]$Precip exists but not year.
What does
str(W[[1]])
return? A data.frame?
And why sep = "" when reading the files, aren't those files csv files?
Hope this helps,
Rui Barradas
