Re: [R] Integrate inside function

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 On Mar 15, 2012, at 6:08 AM, Mauro Rossi wrote: Dear R users

[R] Integrate inside function

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 Best Mauro -- Mauro Rossi Istituto di Ricerca per la Protezione

[R] How can I do these simulations with R code

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

[R] help on stepfunction

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 to
