Questions about doing analysis based on time
APOCooter · Jul 12, 2012 · r-help

Another new question: I want to be able to subset the data based on whether or not that data point was recorded on a holiday. The is.holiday() function from the chron package would be perfect for this. However, when...

APOCooter · Jun 28, 2012 · r-help

That is very helpful, and exactly what I was looking for! However, I seem to have some problems. When I ran the following line: aggregate(SunScore ~ h, data=dat, mean) I got the following output: h SunScore 1 0 136...

Truncating (rounding down) to nearest half hour.
APOCooter · Jul 19, 2012 · r-help

I couldn't find anything in the chron or timeDate packages, and a good search yielded rounding to the nearest half hour, which I don't want. The data: structure(list(Date = structure(c(1209625080, 1209641460, 1209652500, 1209676800, 1209682860, 1209692100...

I have the following data (a subset of the real data set): structure(list(Date = structure(c(1209625080, 1209641460, 1209652500, 1209676800, 1209682860, 1209692100, 1209706980, 1209722580, 1209726300, 1209739620, 1209762780, 1209765720, 1209770520, 1209791040, 1209812580, 1209829920, 1209837180, 1209848160, 1209854640, 1209859440, 1209870780, 1209887760, 1209901080...

Questions about doing analysis based on time
APOCooter · Jul 10, 2012 · r-help

Thanks to everyone for their help so far. It's been greatly appreciated. I have a new, but similar problem: I have data that I have broken down by hour (median/mean for each hour). I would like to break...

APOCooter · Jul 11, 2012 · r-help

Hmm, I guess that's not exactly what I needed. It's my fault; you gave me what I asked for, I was just asking for the wrong thing. What I'm hoping to do is something similar to: aggregate...

APOCooter · Jun 25, 2012 · r-help

Oh, whoops. When I responded the first time, I had done dput(head(Sunday, 100)) too, but it didn't look useful. It was only just now that I saw that it basically prints out the vectors. Sorry about that...
