hypergeometric function in ‘ mvtnorm’
Is there any way to know how the "dmvt" function computes the hypergeometric function needed in the calculation for the density of multivariate t distribution? -- View this message in context: http://r.789695.n4.nabble.com/hypergeometric-function-in-mvtnorm-tp4483730p4483730.html Sent from the R help mailing list archive at Nabble.com.

pvmnorm, error message
Hello there! My operating system is Windows XP, my version of R is the latest (R-2.5.0). Recently I have downloaded the package "mvtnorm" and a problem with the command "pmvnorm" occured. Trying to enter the lines ... A <- diag(3) A[1,2] <-0.5 A[1,3] <- 0.25 A[2,3] <- 0.5 pvmnorm(lower=c(-Inf,-Inf,-Inf), upper=c(2,2,2),mean = c(0,0,0), corr=A) I got the following

pmvt problem in multcomp
Hi, all: Two examples are shown below. I want to use the multiple comparison of Dunnett. It succeeded in upper case "example 1". However, the lower case "example 2" went wrong. In "example 2", the function pmvt return NaN, so I cannot show this simtest result. Is there any solution? (I changed the variable "maxpts" to a large number in front of the

new package `multcomp'
New package `multcomp' for general multiple comparisons written by Frank Bretz, Torsten Hothorn and Peter Westfall We've uploaded the package `multcomp' to CRAN. The R package allows for multiple comparisons of k groups in general linear models. We use the unifying representations of multiple contrast tests, which include all common multiple comparison procedures, such as the

loop over large dataset
Hi All, I'd like to ask for a few clarifications. I am doing some calculations over some biggish datasets. One has ~ 23000 rows, and 6 columns, the other has ~620000 rows and 6 columns. I am using these datasets to perform a simulation of of haplotype coalescence over a pedigree (the datestes themselves are pedigree information). I created a new dataset (same number of rows as the pedigree

mutlivariate normal and t distributions
Dear R-help list members, I have created a package 'mnormt' with facilities for the multivariate normal and t distributions. The core part is simply an interface to Fortran routines by Alan Genz for computing the integral of two densities over rectangular regions, using an adaptive integration method. Other R functions compute densities and generate random numbers. The starting

RE: mvtnorm package installation failure
Hi, Thank you for the tip. I tried to re-intall R from Debian "stable", in which R's version is 1.4.0. And the installation of "mvtnorm" works. I then re-installed R yet again from Debian "unstable" (woody), in which R's version is 1.5.1. The installation of "mvtnorm" fails again with the same error message. Another package that failed with the

questions about R
Hi, I try to compute critical value for multivariate normal distribution, and I find the crit(fit, const = c(0, 1), d = 1, cov = 0.95, rdf = 0) which seems to compute critical value. However, I can't compute right critical value for multivariate normal distribution which I want. I don't know how to solve my question. I send my question in the file. Would you help me to solve it, please?

interfacing C into R and R packages
Hi, I would like to interface a C code into R. Is it possible to use in the C code, functions from a R package (for instance, to use pmvnorm within loops in the C code and to call the result in a R function)? Nathalie

multiple comparisons/tukey kramer
Hi, I'm trying to make sense of the options for multiple comparisons options in R. I've found the following options: pairwise.t.test, which provides standard t-tests, with options for choosing an appropriate correction for multiple comparisons TukeyHSD, which provides the usual Tukey test glht(package multcomp), which provides a variety of options >From the help list, it appears

adapt package missing because of licensing issue: fix?
I think this is probably known by someone, but I wanted to ask/comment: The 'adapt' package has been removed from CRAN because of an 'unclear' license. That makes sense, but it actually took a bit of digging for me to discover that, and if I had been a student I might not have figured it out. The package is simply missing from the CRAN compiled packages page; I did find

Issues with 'Miwa' algorithm in mvtnorm package
Currently doing some work on local maxima on a random field and have encountered an issue with the Miwa algorithm used with the pmvnorm function in the mvtnorm R package. Based on recommendations by Mi et al., we ran the mvtnorm package using the Miwa algorithm, since we have a maximum of 4 dimensions with non-singular matrices. However, running the estimation procedure in this way, we obtained

Issues with 'Miwa' algorithm in mvtnorm package
Rather specialized. As this appears to be primarily a statistical, not an R programming question, you may do better posting on a statistical site like http://stats.stackexchange.com/ if you don't get a satisfactory reply here . Alternativey, if you think this is a package bug, perhaps contact the package maintainer directly, as (s)he may not monitor this list. -- Bert Bert Gunter

Problem with Numerical derivatives (numDeriv) and mvtnorm
I'm trying to obtain numerical derivative of a probability computed with mvtnorm with respect to its parameters using grad() and jacobian() from NumDeriv. To simplify the matter, here is an example: PP1 <- function(p){ thetac <- p thetae <- 0.323340333 thetab <- -0.280970036 thetao <- 0.770768082 ssigma <- diag(4) ssigma[1,2] <- 0.229502120

Issues with 'Miwa' algorithm in mvtnorm package
Hi Eric, Thanks for having a look into this. I think you have a small typo...

Rsyncing to arbitary locations using modules
Hi, I have been experimenting with the various rsync options and so far have had no luck, so I thought I would ask the experts out there. We have remote devices out in the field and communicate with them via GPRS. I am writing an app that will push new audio files out to remote devices using rsync. The app also periodically uses rsync to grab log files. So here is my scenario: The Remote

rect() question.
Hello. I have another rect question. If I want to make a lot of rectangular, without borders, and without any spaces between them, how could I do it? I.e. > plot(-1:1., -1:1., type = "n") > rect(0,-1,1,1,col="red",lwd=0,border=F,xpd=T) > rect(-1,-1,0,1,col="blue",lwd=0,border=F,xpd=T) will produce two rectangular, but there is space between them.
