R CMD check fails at package dependencies check on Fedora Core 5, works on other systems
...; flag is set somewhere, leading to lots of
spurious messages like this
request done: ld 0xa227598 msgid 1
which may be confusing R.
However, R CMD check seems to fail for packages with no dependencies at the
dependencies check stage.
I've tried this with two packages, my own gld and also zipfR. Both fail in
the same way.

zipfR help
Hi,
I have a question on generating random variables based on zipf-mandelbrot
distribution.
So when I execute the following lines:
ZM = lnre ("zm", alpha = 2/3, B=0.1)
zmsample = rlnre (ZM, n =100)
zmsample
It generates 100 random values based on a zipf-mandelbrot distribution as
below. But how do I make sure the generated random number is within the
range of 1 - 6000 only? Can I

Regularized gamma function/ incomplete gamma function
...1)e^(-x))dx ; 0<r<Inf (which is eventually the ratio of the
Incomplete gamma function by the gamma function), does anyone know of a package in R that would evaluate the derivative of the inverse of Reg with respect to k? I am aware that the function "Rgamma.inv" of the package "Zipfr" evaluates the inverse
of Reg and I'm wondering wether there is a function that would evaluate the derivative of the inverse..
Alternatively, a good numerical integration package/ or simply a function that could evaluate the integral int_0^r (log(x) x^(k-1) e^(-x))dx; 0<r<Inf
would...

Incomplete Gamma function
Hello
I am trying to evaluate an Incomplete gamma function
in R. Library Zipfr gives the Igamma function. From
Mathematica, I have:
"Gamma[a, z] is the incomplete gamma function."
In[16]: Gamma[9,11.1]
Out[16]: 9000.5
Trying the same in R, I get
> Igamma(9,11.1)
[1] 31319.5
OR
> Igamma(11.1,9)
[1] 1300998
I know I have to understand the theory and the mat...

Zipf fitting using R
Dear R-users,
I am new to R and would like to use it for fitting the zipf distribution to
some numeric data that I have. Here's the snippet that I use:
library(VGAM)
X <- read.table(file("~\\mydata.txt", encoding="latin1"))
w <- as.vector(t((X[2])))
w <- w/sum(w)
y <- (1:length(w))
fit = vglm (y ~ 1, zipf, tra=TRUE, weight=w)
zipf(N=NULL,

plotting Zipf and Zipf-Mandelbrot curves in R
Using R, I plotted a log-log plot of the frequencies in the Brown Corpus
using
plot(sort(file.tfl$f, decreasing=TRUE), xlab="rank", ylab="frequency",
log="x,y")
However, I would also like to add lines showing the curves for a Zipfian
distribution and for Zipf-Mandelbrot.
I have seen these in many articles that used R in creating graphs.
Thank you!

A introductory question about Zips law (Newbie to statistics)
Hi everyone.
Newbie to statistics.
I have 40 matrices of ~400 values. how may I determine whether the
distribution follows zips law?
response <-sample (1:20,400*4, replace= TRUE)
Thank you vry much.
