Dear David and Micheal,
thanks for your suggestion. Vectorize does what I need.
David you suggest me that I didn't built the function in a manner that
would vectorize. Could you please explain me what's wrong?
Thanks,
Mauro

hy doesn't this calculate cumdensity (p.mixedgamma) in case x is a vector?
For instance try:
pmixedgamma3(c(10,20),shape1=10,rate1=1,shape2=10,rate2=1,prev=0.5)
As you can see cumdensity is calculated just for the first x value.
Thanks in advance

1) The Pareto P(alfa) distribution is defined by its density f(x|alfa)
=alfa*X^(-alfa-1) over (1 to infinity). Show that it can be generated as the
-1/alfa power of a uniforme variate. Plot the histogram and the density.
2) The Poisson distribution P(lambda) is connected to the exponential

"na.rm=TRUE" like in for instance
mean(x,na.rm=TRUE).
Does anybody know how to do this?
Thank you very much.

Dear members,
I would like a help for extracting the values from a step function
(stepfun).
>From help(stepfun) we have the following example:
Y0<-c(1.,2.,4.,3.)
y0<-c(1.,2.,3.,4.)
sfun<-stepfun(1:3,y0,f=0)
plot(sfun)
Now, suppose instead I was given the object (*sfun*, say) from which I
wanted
oints = FALSE, add=TRUE,col.h="red",col.v="red")
Thanks,
Mauro

Hi, My name is Mauro Belleggia, I m doing an ANOSIM (using "vegan" package)
to test statistically whether there is a significant difference between 3
(1,2 and 3) groups of sampling units. My results were:
Call:
anosim(dis = distancias, grouping = Lt)
Dissimilarity: bray
