Hi All, very rusty in R.. my results get overwritten when try to store within the loop. This my code: ListS=unique(data$Spec) Stat<- numeric(0)
for(i in 5){ SS=subset(data,data$Spec==ListS[i]) maxC<- which.max(SS$Cc) smoothC=mean(SS$Cc[maxC + c(-2:2)]) currC=tail(SS,1)$Cc Index=currC/smoothC Stat[i]=c(Stat, Index[i]) } Stat This is what I get: [1] NA NA NA NA NA I am obviously not indexing well here. Thanks!!!
