I'd replace 3 the lines above with:
hcdif = Hi(data)-Cl(data)

>data$smv=filter(data[,5],rep(1/7,7), sides=1) 
>data$lmv=filter(data[,5],rep(1/21,21), sides=1)
>The data$smv has not error

Do you want:
datasmv=filter(Cl(data),rep(1/7,7), sides=1) 
datalmv=filter(Cl(data),rep(1/21,21), sides=1)


Change is inevitable, except from a vending machine.
