I have a problem to select a seasonal summary from daily data. I need to classificated a variable in the seasonFilter (winter) The winter season started at November and end at April

for( i in 1:length(years)){

seasonFilter <- neu20[(neu20$Year == years[i] & neu20$Moth %in% c(11:12) $ 
                ((neu20$Year == years[i+1] & neu20$Month %in% c(1:4), ]))

season <- data.frame(YEAR = as.integer(years[i]), YEAR+1 = as.integer(years[i+1]), 
          numDies = as.integer(nrows(seasonFilter)))

outputFinal <- rbind(outputFinal, season)
}

THANKS!

  • How about just finding the season for each entry and then subsetting based on that? https://stackoverflow.com/questions/9500114/find-which-season-a-particular-date-belongs-to – Roman Luštrik Jul 03 '18 at 13:44
