Yes, it is possible to work time series data. We have previous done some work on network traffic data, here are a couple of examples:
http://lbl.gov/%7Ekwu/ps/LBNL-59891.html http://lbl.gov/%7Ekwu/ps/LBNL-61080.html Yes, you can remove data records. You can mark some rows as "inactive" without actually remove the values, see for example, http://crd-legacy.lbl.gov/~kewu/fastbit/doc/html/classibis_1_1part.html#adae78b96baaa1ec9e835232c38b008c7 Alternatively, you can actual remove the inactive values and rewrite the data files, through the function ibis::part::purgeInactive. Good luck.
