Problem in using MASS
Dear Sir
I am very new user of R project. Sir I am a research scholar. I am doing work on fitting distributions. Sir in using MASS package I am facing the following errors for my data.
fitdistr(urban$x, "gamma")Error in fitdistr(urban$x, "gamma") : 'x' must be a non-empty numeric vector
Would you please help in this regard.
Kind Regards

How can I simulate Pareto distribution in R?
Hi, guys,
I need to simulate Pareto distribution. But I found 'rpareto' didn't exist in R. And it seems that Pareto distribution don't have mathematical relationships with other distributions. What can I do?
Thanks a lot.

ks.test()
Dear All
I am trying to replicate a numerical application (not computed on R) from an
article. Using, ks.test() I computed the exact D value shown in the article
but the p-values I obtain are quite different from the one shown in the
article.
The tests are performed on a sample of 37 values (please see "[0] DATA"
below) for truncated Exponential, Pareto and truncated LogNormal

how to plot multiple density functions in one graph
Hello,
I am new to R and have two easy questions.
How can you plot multiple density functions in one graph? I have five beta
densities that I would like to plot in one graph. I understand how to plot
one beta density as a line:
plot (x,(dbeta(x,shape1=,shape2=,), type ="l")
Does the Pareto distribution need to be added to R with an additional
package?
thanks,
John

rmutil parameters for Pareto distribution
In https://en.wikipedia.org/wiki/Pareto_distribution, it is clear what the
parameters are for the pareto distribution: *xmin *the scale parameter and
*a* the shape parameter.
I am using rmutil to generate random deviates from a pareto distribution.
It says in the documentation that the probabilty density of the pareto
distribution
The Pareto distribution has density

An example of "overloading" [
Hello:
Could anyone point me to a nice example where someone has created methods
for "[" on a user defined Class?
I looked at the package Matrix but that was a little daunting. I'm looking
for someone a little more introductory. I've tried to search the help
section and the web but its difficult since "[" isn't searchable.
Thanks in advance!

[LLVMdev] conflict of gcc and llvm-gcc
Hello everyone,
I build llvm-2.9 from source code. After install, i find the
executable file is 'gcc', NOT 'llvm-gcc'.
It is not convenient because there has been another gcc in system. To
avoid conflict i rename
gcc to llvm-gcc now.
Can i avoid the problem by options when build?
Thanks

Distribución log-logistica
Hola a tod@s,
Hace poco en la lista se discutieron algunas aproximaciones para determinar
la distribución de probabilidad que potencialmente podrían haber generado
los datos (ver [1]) y una de ellas fué el AIC. Haciendo uso del programa
enviado por Pablo Verde (ver [1]), estos son los resultados para mis datos:
weibull , AIC = 69839.44
exponential , AIC = 79488.77
gaussian , AIC = 69413.03

cdf
Dear all,
I have the cdf of the following power fuction distribution:
F(y)=(y/350)^a ,0<y<350,
where " a " is some parameter with range a>0.
I want to use it as the argument of the discretize function of the actuar package.
So I think I need to define this function to R so that if I entered a=1, I get the following
F(y)=(y/350)
and if I entered a=4.5, I get the

Small encoding question
Dear developeRs,
Compilation of the latest version (0.9-5) of my actuar package fails
with r-release MacOS_X ix86 on CRAN; see

All errors come from accented letters in comments in latin-1 encoded
files (except hierarc.R which is in UTF-8, my bad). Encoding is
declared as latin-1 in DESCRIPTION.

mixed exponential distribution
Good morning,
Is there anyway to do Mixed Exponential Distribution in R? I am trying
to load some lag-weighted empirical survival distribution into R and run
a mixed exponential on that data.

SLLN for loggamma fails for 2 order moments
Hi.
I was trying to calculate 2. order moment for a loggamma sample.
Also, I checked it with the function mlgamma from the package actuar, which
calculates moments based on loggamma parameters.
Se below - I get big deviations. Numerical integration suggests that mlgamma
gets it right. What fails
in my attempt to use SLLN to estimate the 2. order moments?
Code:
sum(rlgamma(10^6,25,2.6)^2)/10^6

Fitting an Inverse Gamma Distribution
http://r.789695.n4.nabble.com/file/n3216865/Inverse_Gamma.png
Hello,
I am seeking help in estimating the parameters of an inverse gamma
distribution (from the 'actuar' package) using a function like 'fitdistr'.
Unfortunately I haven't found such a package using findFn('fit Inverse
Gamma') from the 'sos' package and was therefore hoping someone might be

Insurance review statistical methods
Hi R users:
I will like to know if somebody works on insurance statistics
(actuarial problems) and had use TRICAST, and can tell me
if with all the R tools it can be build a solution
like TRICAST or similar.
In a word:
Do you think that R has all the statistical tools
(I mean modeling tools) to make a job similar to TRICAST?
Does TRICAST has modeling tools that are not implemented
on R yet?

paths for install and libraries?
I've written a fairly elaborate package (called "eoa") that relies on
functions from several other packages. I've built the package into a zip

the zip to a couple dozen people for testing. My package installs fine, but
some people are having trouble loading it. After library(eoa), they get

Call a Fortran subroutine with R: R crashes
Hello,
I am trying to call a FORTRAN subroutine within R and something really
strange happens:
I have a dll-library, that I load with dyn.load('mpbvv.dll'). I have checked
the [Ordinal/Name Pointer] Table for the function within the library that I
want to call - it is there (objdump - p mpbvv.dll).
Then, I have written an R-wrapper to call the FORTRAN subroutine, which
works fine. SInce

Histogram for grouped data in R
I have grouped data in this format
Size -- Count
0-10 -- 15
10-20 -- 25
20-50 -- 10
50-100 -- 5
I've been trying to find a way to set this up with the proper histogram
heights, but can't seem to figure it out. So any help would be much
appreciated!
