Re: [R] modeling interval data, a.k.a. irregular timeseries

It seems to me you that have a sequence (``series'') of random times, rather than a sequence of values of a random variable observed at a irregularly spaced times. Hence I would say that point process modelling, rather than time series modelling, would be more appropriate. You could

Re: [R] (with subject)

I assume the problem is that you want the axis to have all 12 months but your data is much shorter. Try this: mos - seq(as.Date(2008-01-01), length = 12, by = month) plot(range(mos), range(rawData$y), type = n, xaxt = n) lines(rawData$Date, rawData$y) axis(1, mos, month.abb) On Thu, Sep 4,

[R] how to deal with NaN in boot object

Hi there, I use boot() to do bootstrap simulation on my statistic, I get a boot object, named obj. For certain reasons, there are some NaN in obj$t. Now, I hope to get confidence interval using boot.ci(), it give the following error: Error in if (const(t, min(1e-08, mean(t)/1e+06))) { :

[R] algorithm to create unique identifiers

Hi all, I am trying to create a unique identifier for each row, combining numbers from three columns. Do you know if there is a general formula to do this (or some manual where I can read about this)? I figure I can use the numeric entries of the columns as coordinates and multiply them

[R] Derived classes

Coming from a C++ and C# background I would like to know how inheritance works with 'R'. The classical example is I can define an abstract class 'Shape' and have an array of 'Shape's but each instance could be a Circle, Square, Triangle, etc. because they all derive from 'Shape'. At runtime if

[R] library/function that estimates parameters of well known distributions from empirical data?
