Hi,
I encounter a problem. I use optim() function in R to estimate likelihood
function and the method is SANN in the optim function.
out <-
optim(parm,logLik,method='SANN',hessian=T,control=list(maxit=500))
However, I find that each time I run the program, I will get different
values of param

I can successfully load the RData file:

Check out the envir= argument to load() and save() if you want to
isolate the loaded data from the rest of the session.
For an example:

Simulated annealing is a probabilistic method and will do things like that. You
should probably read an introduction to the method, e.g. the Wikipedia page.
Not too unlikely, you really want to use one of the other methods in optim()
(or better still optimr from the optimx package).

Hi Jason,
I assume that you actually have "WVS.RData" in your working directory
when you try to load it. Otherwise you will get an error message. If
you don't get an error message when you do this:
load("WVS.RData")
there will be a new object in your workspace. So if you want to see

Dear friends,
I have a sample dataset, which is basically the number of transits through

MyDat <- dataset$DailyTransits
What I´d like to do is to test whether MyDat follows a poisson distribution
or not.
SANN is almost NEVER the tool to use.
I've given up trying to get it removed from optim(), and will soon give up
on telling folk not to use it.

You may misunderstand how RData files work. Note that RData files are
not necessarily JUST a single variable unless they were explicitly
written to store a single variable only.
If you save a single variable (a dataframe, for example) named 'mydata'
with save(mydata, file = "saveddata.RData")

Bert, thanks for responding to my email. I do realise that newbie's like my can

Hi,
Your sample code suggests that you don't yet understand how R works,
and might benefit from a tutorial or two. However, your verbal
description of what you want is quite straightforward. Here's a
R-style way to count the number of times each company appears, and to
get the mean value of Turnov

Hello everyone,
I saw this scatterplots from a paper and thought it looked very nice:
https://drive.google.com/file/d/1V7F1gq-J_GIFDOrJs00hwGyXUqCZ_xwa/view?usp=sharing
It was similar to stripchart() with 'jitter' method, but it has a special
pattern of aligning points which made it look nice
