Hi everyone,

Thanks very much for all your replies.

I'm interested in hearing more about the lag function. I remember coming across this in the R intro manual, but I couldn't figure out how to apply it to my case. Does anyone know how it is applied, assuming a time series data frame?

Thanks,

rcoder
