Concerning the several comments on your note relating to histograms, an informative and entertaining illustration, using Java, of how your subjective assessment of the data can change with different histograms constructed from the same data, is provided by R.

Subject: [R] Re-binning histogram data


Short Version:
Is there a function to re-bin a histogram to new, broader bins?

Long version: I'm trying to create a histogram, however my input-data is itself in the form of a fine-grained histogram, i.e. numbers of counts in regular one-second bins. I want to produce a histogram of, say, 10-minute bins (though possibly irregular bins also).

I suppose I could re-create a data set as expected by the hist() function (i.e. if time t=3600 has 6 counts, add six entries of 3600 to a list) however this seems neither elegant nor efficient (though I'd be pleased to be mistaken!). I could then re-create a histogram as normal.

I guessing there's a better solution however! Apologies if this is a basic question - I'm rather new to R and trying to get up to speed.
