Missing historical data when FREQ > 2

[GoogleCodeExporter]

For instance, you loose half of historical data when switching the FREQ from 2 
to 4

GOOD:

/opt/strategico/strategico.R --cmd eval.ts --project.name web-ltp --id.list 1 
--ts.string 2,22,34,53,54,34,22,66,55,33,55.3,2,22,34,53,54,34,22,66,55,33,55.3 
--ts.start 2001-1 --ts.freq 2

WRONG:

/opt/strategico/strategico.R --cmd eval.ts --project.name web-ltp --id.list 1 
--ts.string 2,22,34,53,54,34,22,66,55,33,55.3,2,22,34,53,54,34,22,66,55,33,55.3 
--ts.start 2001-1 --ts.freq 4

Livio

it is due to your new functions in strategico_util.R and ltp.R:

Number.ToPeriod <- function(period){  return(c(period%/%2,period%%2+1))  }

Period.ToNumber <- function(period){
  if(is.numeric(period)) 
    return(sum((period-c(0,1))*c(2,1))) 
  else
    return(sapply(period,function(per)   sum((Period.FromString(per)-c(0,1))*c(2,1))))
  }

Please 

-) add the parameter "period.freq" to the new functions
-) rename Number.ToPeriod to Period.FromNumber
