Hello! I am trying to put two math expressions in the title of a plot. As you can see below, I can place correctly one expression at a time, but not both. Ideally I would like to have them separated...

Hello! I am using R on two different machines (under Ubuntu and OS X, but this is probably irrelevant) and I would like to keep the two installations 'synchronized', in particular in terms of installed packages. For example, if I...

Hi, There are a few packages that I would suggest to run Kalman filter. Take a look at dlm and KFAS. If you need more help you should be more precise in formulating your problem, providing a small example, as...

For a Pareto distribution, even a truncated one, the inverse CDF method should be straightforward to implement. Giovanni Petris On Tue, 2010-11-09 at 10:50 -0600, cassie jones wrote: > Dear all, > > I am trying to simulate from truncated...

Is there a way of `restarting' split.screen? This is what I am getting: > close.screen() [1] 10 11 12 13 > close.screen(all=TRUE) Error in par(args) : parameter "i" in "mfg" is out of range > graphics.off() > x11...

My problem is that with the following commands I get the title of the plot printed within the plotting region. (everything works fine with x11()). Any suggestions? Thanks in advance, Giovanni > postscript(file="Neyman-Scott.ps") > plot(cardiff$poly, asp...

I have a function that, via .Call, modifies its argument, so I first create a backup copy of the object I want to pass, make a copy of it, and pass the copy to the function. However, my function also...

Hello all, In a recent issue of the Bulletin of the American Mathematical Society, Persi Diaconis opens a review/discussion paper on MCMC with a nice application to cryptography and message decoding. The article is available online at http://www...

Have you tried a search of CRAN? Seaching r-help archives may result in useful information as well. As formulated, the questions are difficult to answer. There are packages that use MCMC, Gibbs Sampling, Metropolis Hastings for specific classes of...
