can't find the error in if function... maybe i'm blind?
Hi everybody, the following alway gives me the error "Fehler in if (File$X.Frame.Number[a] + 1 == File$X.Frame.Number[a + 1]) (File$FishNr[a] <- File$FishNr[a - : Fehlender Wert, wo TRUE/FALSE n?tig ist". Maybe its stupid, but i'm not getting why... Maybe someone can help me. Thanks a lot! for (i in unique(BigFile$TrackAll)) { File <- subset(BigFile,BigFile$TrackAll == i) File$FishNr [1] <- 1...
