I want to run an estimation assuming that my variables are distributed according to the Dirichlet distribution. To do so, I need to use the cdf function. For all the distributions in R, there are the respective r,p and d functions that produce random variables, pdf and cdf.
Nevertheless, for the Dirichlet, I can only find the random number generator and the pdf.
Is there a similar package for R that gives the cdf?
Many thanks,

I am looking to run diagnostics for categorical variable classifications in R. I am particularly interested in getting User's and Producer's accuracy and kappa statistics. There used to be a package (nnDiag) in R that calculated all of these metrics. It appears as if the package was removed from CRAN. Does anyone know why it was discontinued and if there is a comparable package in R? I am running R 3.1.1.
Caret does Cohen's Kappa and summary stats quite well.

Does any function in R (or Matlab) for the estimation of threshold vector autoregressive model (TVAR) by OLS for a number of threshold superior than 3?
In vgxvarx function, can I treat the 1st column of presample time series process matrix the threshold for my autoregressive model?
There are such functions in Econometrics Toolbox. Check out help vgxvarx.

Is there a package in R that allows me to plot multiply time series next to each other 3D?
Like in the following examples:

Have you checked out chartSeries3d0 from the quantmod package?
Here's an example I found on quantmod.com:
library(quantmod)
source("http://www.quantmod.com/examples/chartSeries3d/chartSeries3d.alpha.R")
getSymbols("DGS1MO;DGS3MO;DGS6MO;DGS1;DGS2;DGS3;DGS5;DGS7;DGS10;DGS20;DGS30",src="FRED")
TR <- merge(DGS1MO,DGS3MO,DGS6MO,DGS1,DGS2,DGS3,DGS5,DGS7,DGS10,DGS20,DGS30, all=FALSE)
colnames(TR) <- c("1mo","3mo","6mo","1yr","2yr","3yr","5yr","7yr","10yr","20yr","30yr")
TR <- na.locf(TR)
chartSeries3d0(TR["2011"])

R provides a very powerful package called laplacesdemon for bayesian inference using the laplace distribution. I was wondering if there is any equivalent package for Matlab?
Thanks!
The question was a bit short so I'm not sure if this is exactly what you are asking for but here goes:
No - there is no Laplacedemon equivalent in Matlab
Yes - there are lots of Matlab packages that partly overlap with LaplaceDemon. As I don't know exactly what you want to do my recommendation is likely to have a high variance. Having established that I suggest that you take a look at http://becs.aalto.fi/en/research/bayes/gpstuff/ :). If you feel comfortable with using MCMC directly, you can take a look at http://helios.fmi.fi/~lainema/mcmc/. (I believe that matlab has some functions for this directly in their statistics or/and econometrics toolboxes)
You could also run R directly from Matlab http://neurochannels.blogspot.se/2010/05/how-to-run-r-code-in-matlab.html or http://rwiki.sciviews.org/doku.php?id=tips:callingr:matlab

Is there any scripting language function (like in python or bash) that samples from a zipf-like distribution, for exponent 0<a<=1. Zipf-like distribution p(a) can be found, here.
PS: I am aware of existence of numpy function that can generate zipf samples, but it's only for a >1.
