INDEXNUM function

Rebase a Time Series

This function rebases an input time series to the value of 100 in the year selected by the BASEYEAR argument. If the input time series frequency is greater than one, the initial reference is set to the average value of the input time series observations that lie in the BASEYEAR.

INDEXNUM(x=NULL, BASEYEAR=NULL, avoidCompliance=FALSE, ...)

Arguments

• x: Input time series that must satisfy the compliance control check defined in is.bimets.
• BASEYEAR: Rebasing year.
• avoidCompliance: If TRUE, compliance control check of input time series will be skipped. See is.bimets
• ...: Backward compatibility.

Returns

This function returns a BIMETS time series.

#create yearly ts
        n<-20
        ts1<-TSERIES(1:n,START=c(2000,1),FREQ=1)
        TABIT(ts1, INDEXNUM(ts1,2005))
        
        #quarterly
        ts1<-TSERIES(1:n,START=c(2000,1),FREQ=4)
        ts1[5]<-NA
        TABIT(ts1, INDEXNUM(ts1,2000))
