library(xts) library(TTR) ndx = getYahooData("^NDX") aa = ndx$Close bb = aggregate(aa, as.yearweek, tail, 1) The last operation takes forever, and then the bb dates are messed up. The following produces the desired result: time(aa) = as.Date(time(aa)) bb = aggregate(aa, as.yearweek, tail, 1) The index of ndx and aa is of POSIXct (as reported by is(time(ndx))) , which apparently

It is pretty clear people need this. Let's get this moving. I'll try to sum up the point that have been made and I'll try to address them carefully. 1/ There is no good solution for large aggregates. That is true. However, I don't think this is a reason to not address smaller aggregates, as they appear to be needed. Realistically, the proportion of aggregates that are very large

Hi: I am wondering if there are any such application exist in rails or ruby landscape? http://www.rssbus.com/ RSSbus in short a service bus for aggreating RSS feeds, web services what not... instead of doing per service integration the bus takes care of all the RSS/web service connections and provide a unfied feed to your app? I googled but found more PHP and .Net and Java stuff not ruby anyone knows of any such apps? All the best and thanks for...

...ed via the other master due to MX priorities). Conclusion: After 12 hours of running a patched FBSD port I do get those error messages but replictaion seems to work now. But, I still have the feeling that there might something else going wrong. @Timo: Wouldn't it be worth to add replicator/aggreator error messages to head like Aki sent to Remko? That might add some light into replication issues today and in the future. Regards, Michael

Dear all, I'm looking for primary help at aggregating table() results and at writing a loop (if useful) My dataset ( http://goo.gl/gEPKW ) is composed of 23k rows, each one representing a point in the space of which we know the land cover over 10 years (column y01 to y10). I need to analyse it with a temporal sliding window of 5 years (y01 to y05, y02 to y06 and so forth) For each period
