It would be really great if I could do that, because in this case I don't have to re-index my transformed series to the dates again in a new dataframe. Thanks in anticipation. Vishal Belsare

...The code you already suggested would help me make the date sequence, but I am not sure how I could extract the mmddyy string from it. Also, I might end up making a list for dates extending to about 10 years in the past (~2600 working days), so I was more keen on not creating one long list.

...r I can create variable names dynamically and assign values to them. #begin tsn <- (10); for (i in 1:250) { tsn <- c(tsn, tsn[i] + rnorm(1, mean=0.01, sd=0.025)) }; plot.ts(tsn, lwd=2, col="maroon"); #end Thanks in anticipation. Best Regards Vishal Belsare

...on this is that I can then shape my further sub-setting in a form like which(... date == "1998 Q2") or so instead of forcing myself to write "1998/06/30" which would indicate end of second quarter (I just think that is redundant). Thanks in anticipation. Best Regards Vishal Belsare
