Integrate inside function
Dear R users,
first I take this opportunity to greet all the R community for your
continuous efforts.
I wrote a function to calculate the pdf and cdf of a custom distribution
(mixed gamma model).
The function is the following:
pmixedgamma3 <- function(y, shape1, rate1, shape2, rate2, prev)
{
density.function<-function(x)
{
shape1=shape1
rate1=rate1
shape2=shape2

Beta fit returns NaNs
Hi,
sorry for repeating the question but this is kind of important to me and i
don't know whom should i ask.
So as noted before when I do a parameter fit to the beta distr i get:
fitdist(vectNorm,"beta");
Fitting of the distribution ' beta ' by maximum likelihood
Parameters:

Problemas con la funcion "apply"
Buenos dias!
Os escribo para ver si me podeis ayudar con un asunto en el que me he quedado un poco encallado.
Lo que tengo que hacer es sacar los percentiles (0.001, 0.005, 0.95 y 0.999) de varias distribuciones beta, concretamente 418. Cada distribucion esta definida por los parametros "shape1" y "shape2". Por lo tanto tengo una base de datos de 418 filas y en cada una de

Plot cumulative probability of beta-prime distribution
Hallo,
I need your help.
I fitted my distribution of data with beta-prime, I need now to plot the
Cumulative distribution. For other distribution like Gamma is easy:
x <- seq (0, 100, 0.5)
plot(x,pgamma(x, shape, scale), type= "l", col="red")
but what about beta-prime? In R it exists only pbeta which is intended only
for the beta distribution (not beta-prime)
This is

unstable corner of parameter space for qbeta?
I've discovered an infelicity (I guess) in qbeta(): it's not a bug,
since there's a clear warning about lack of convergence of the numerical
algorithm ("full precision may not have been achieved"). I can work
around this, but I'm curious why it happens and whether there's a better
workaround -- it doesn't seem to be in a particularly extreme corner of

Double Colors in Main
Dear All,
Consider the following trivial code snippet
rm(list=ls())
name_vec <- c("color1", "color2")
pdf("test_color.pdf")
plot(seq(5), seq(5), main=paste(name_vec[1]," and ",name_vec[2], sep=""))
dev.off()
What I would like to achieve is rather simple to explain, but it is
giving me a headache: how can I have two colors in main? Let us

How to generate a matrix of Beta or Binomial distribution
Hi folks,
I have a question about how to efficiently produce random numbers from Beta
and Binomial distributions.
For Beta distribution, suppose we have two shape vectors shape1 and shape2.
I hope to generate a 10000 x 2 matrix X whose i th rwo is a sample from
reta(2,shape1[i]mshape2[i]). Of course this can be done via loops:
for(i in 1:10000)
{
X[i,]=rbeta(2,shape1[i],shape2[i])
}

problem getting R 2.3.1 svn r38481 to pass make check-all
Hi,
I noticed this problem on my home desktop running FC4 and again on my
laptop running FC5. Both have previously compiled and passed make
check-all on 2.3.1 svn revisions from 10 days ago or so. On both these
machines, make check-all is consistently failing (4 out of 4 attempts on
the FC 4 desktop and 3 out of 3 on the FC 5 laptop) in the

Bayesian logistic regression with a beta prior (MCMClogit)
Dear all,
I am trying to use the logistic regression with MCMClogit (package:
MCMCpack/Coda) and I want to put a beta prior on the parameters, but it's
giving me error message (please see output below) no matter what shape 1 or
2 I use. It works perfect with the cauchy or normal priors. Do you know if
there is a catch there somewhere? Thanks

invalid operands of types ‘SEXPREC*’ and ‘R_len_t’ to binary ‘operator/’ with Rcpp.

I just started learning how to use Rcpp. Earlier while using it, I
encountered an error as shown below:

Two functions as parametrs of a function.
Hi R users:
I'm trying to make a function where two of the parameters are
functions, but I don't know how to put each set of parameters for
each function.
What am I missing?
I try this code:
f2<-function(n=2,nsim=100,fun1=rnorm,par1=list(),fun2=rnorm,par2=list()){
force(fun1)
force(fun2)
force(n)
p1<-unlist(par1)

Problem with fitdistr for beta
I have the following problem:
I have a vector x of data (0<x<=1 ) with
a U-shaped histogram and try to fit a beta
distribution using fitdistr. In fact,
hist(rbeta(100,0.1,0.1)) looks a lot like
my data.
The equivalent to
the example in the manual
sometimes work:
> a <- rbeta(100,0.1,0.1)
> fitdistr(x=a, "beta", start=list(shape1=0.1,shape2=0.1))1)

select most frequent value in set of variables
Hi,
I would like to select the most frequent value level in a set of three variables.
Three different observators have judged hair color in study subjects. Mostly they judge the same color, sometimes there is a slight difference. I want to know what most of the observators have chosen (so at least 2) from the 3 observations. E.g. If two out of three observators decide the hair is black, then

dbeta may hang R session for very large values of the shape parameters
Dear all,
we received a bug report for betareg, that in some cases the optim call in betareg.fit would hang the R session and the command cannot be interrupted by Ctrl-C?
We narrowed down the problem to the dbeta function which is used for the log likelihood evaluation in betareg.fit.
Particularly, the following command hangs the R session to a 100% CPU usage in all systems we tried it (OS X

How to convert List object to function arguments?

I have a function "goftests" that receives the following arguments:
* a vector "x" of data values;
* a distribution name "dist";
* the dots list ("...") containing a list a parameters to pass to CDF
function;
and calls several goodness-of-fit tests on the given data values against
the given distribution.
