I have a list of numbers corresponding to timestamps, a sample of which follows: c(1327211358, 1327221999, 1327527296, 1327555433, 1327701042, 1327761389, 1327780993, 1327815670, 1327822964, 1327897497, 1327897527, 1327937072, 1327938300, 1327957589, 1328044466, 1328127921, 1328157588, 1328213951, 1328236836, 1328300276, 1328335936, 1328429102)
I would like to group these into hours. In other words, something like: c( "2012-01-31 21:14:26 PST" "2012-02-01 20:25:21 PST" "2012-02-02 04:39:48 PST" "2012-02-02 20:19:11 PST" "2012-02-03 02:40:36 PST" "2012-02-03 20:17:56 PST" "2012-02-04 06:12:16 PST" "2012-02-05 08:05:02 PST") Hour Hits 21 1 20 3 4 1 2 1 6 1 8 1 How would I do this without too much pain (from a CPU perspective)? This is a subset of a million entries and I would rather not go through these manually... So, any advice?
