Re: [R] Simulation Progress
I've made a function that executes a monte-carlo simulation.
It always needs a lot of time until e.g. 1Mio simulation steps are done.
So I would like to know, how many percent of the work is already done.
This reminds me of my 'iterator' class I was working on - but never
really finished.
Instead of doing:
for(i in 1:1000){
dostuff(i)
}
which creates a vector of c(1,2,...,1000), you create an iterator
object, and do a while loop:
myLoop = loop(N=1000)
while(iterate(myLoop)){
dostuff(iteration(myLoop))
}
now all the information about the loop is encapsulated in the iterator
object 'myLoop', and there are methods for working out when the loop
might finish:
predictEnd(myLoop)
Predicted finish at 12-Dec-02 12:12:34
I also started work on a superclass of this for MCMC runs, where you
could specify a burn-in period and a sampling thinning parameter, and
then there were methods for telling if you were in the burn-in period or
if this was an interation that you were sampling in your output.
Maybe I'll have a go at cleaning this all up over the easter break and
making a proper package of it.

RE: [R] Simulation Progress
Hi!
What about use of %%, so you print every nth iteration on screen, you can
afcoures calculate how many % of iterations has already passed etc.
Some dummy example:
i - 0
x - 1:100
for (i in x) {
if (i %% 100 == 0) {
print(i)
}
}

Hi,
I've made a function that executes a monte-carlo simulation.
It always needs a lot of time until e.g. 1Mio simulation steps are done.
So I would like to know, how many percent of the work is already done.
In an Excel/VBA Solution I could easily implement a status bar or status
window.
How could an R-Solution look like?
Carsten

Carsten I think that progress() in svMisc package (bundle SciViews on CRAN) will make what you are looking for: it displays progression right in the console.
