i have problem on vector in R program when I needed written code on calibration flow by SWAT result output 

below here is my error 

Qo<-read.table("obs17.txt")[,3]
> Qs1<-read.table("output.rch",skip=45)
> Qs<-Qs1[Qs1$V2==7,7]
>
> # Step 3: calculate Model performance Stastistics
>
> SSR<-sum((Qs-Qo)^2)
Warning message:
In Qs - Qo :
longer object length is not a multiple of shorter object length
> NS<-1-(SSR/(sum((Qo-mean(Qo))^2)))
> PBIAS<-100*(sum(Qs)-sum(Qo))/sum(Qo)
> SSR;NS;PBIAS

Hi Kimi
I'd suggest that you consider posting this on an R forum as we don't offer programming support here outside of AdWords scripts and I don't know any members of the community who could help in this regard.
