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 all, I'm currently trying to bootstrap llvm-gcc-4.2 from the latest stable LLVM release 2.6 on Solaris SPARC. The compilation with a self-build gcc-4.2.4 goes pretty well, however, I hit a seemingly widely know error during llvm-gcc's bootstrap in getting an assertion during the compile of /data/LLVM/src/GCC/RELEASE_26/gcc/libgcc2.c: /data/LLVM/src/GCC/RELEASE_26/gcc/libgcc2.c: In

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
