Hello Everyone,
I am trying a shift the time series in a dataframe (df) by 30 minutes . My
current format looks something like this :
*df$$Time 1*
*201112312230*
*201112312300*
*201112312330*
*I am trying to add an additional column of time (df$Time 2) next to Time
1 by lagging it by – 30minutes. Something like this :*
*df$Time1 **df$$Time2*
*201112312230 **201112312200*
*201112312300 **201112312230*
*201112312330 **201112312300*
*201112312330 *
*Based on some of the suggestions available, I have tried this option *
*require(zoo)*
*df1$Time2 <- lag(df1$Time1, -1, na.pad = TRUE)*
*View(df1)*
*This does not however give me the desired result. I would appreciate any
suggestions/advice in this regard.*
*Thanks,*
*Bhaskar*
