Getting rate of return
Dear R help.
I have a beginner's question to ask you. I faced a difficulty in getting
rate of return for some target data.
I finished data importing and some manipulations. but I have any idea after
that.
Anyone who answer this question?
Thanks in advance

reading large data sets
I have some difficulties in reading big dataset; I have to import a dataset with 1'661'852 observations saved in a 51.4Mb - txt file.
I was wandering if this is a memory size problem or if I realy can't import such big datasets.
If the memory allocated to my R is not enough, I would like to know exactly which comands I should use in order to read and use my large dataset.

Accents in R
Hi,
How can I include accents and signs like '?' '?' in the plots generated by R?
I try, but R automatically transforms the name
ex:
> countries <- c("M?xico", "Espa?a")
> countries
[1] "M\216?xico" "Espa\216?a"

I've seen in some Spanish texts about R how is it normal to include labels of

median and joint distribution
Dear R-"helpers"!
May I kindly ask the pure statistics-experts to help me for a
purpose which first part is not directly concerned with R.
Consider two distribution functions, say f and g. For both, the
median is smaller than a half. Now, the multiplicative or additive
linkage of both distribution leads to a new distribution function,
say h, whereas the median of h is greater than a

weighted samples
Hi everybody,
I have some troubles by using R with weighted data. It is very
easy to obtain the mean of a weighted data set due to the function
weighted.mean, but unfortunately, such a function is not available
for any other estimators. Is there a comfortable way to consider
the column with the weights which would not lead to an expansion
of the sample (what would apply by using the rep()

Re - segments within a lattice graph
Hi,
The solution to my problem is to use
'lsegments' instead of 'segments' within lattice commands.
(Although I wont forget again,
a comment in the segments help file referring to 'lsegments'
might help others not to make the same mistake in the future.)
My thanks to Renaud Lancelot.
Regards,
John.

summary: Sweave - documenting a long function
Hi,
Here is a summary of the replies to my question yesterday
about documenting a long function with Sweave.
My thanks to those who replied.
Friedrich Leisch suggested a work around
which was copied to the mailing list
so I wont repeat it here. This worked well.
(I made a minor addition by adding braces
around each chunk of code to make the
output in the pdf file look a bit prettier.

Kolmogorov-Smirnof test for lognormal distribution with estimated parameters
Hello all,
Would somebody be kind enough to show me how to do a KS test in R for a
lognormal distribution with ESTIMATED parameters. The R function
ks.test()says "the parameters specified must be prespecified and not
estimated from the data" Is there a way to correct this when one uses
estimated data?
Regards,
Kwabena.

problem with Sweave on 1.6 on NT4
Hi,
I recently compiled 1.6 on NT4 but
I am having a problem with Sweave.
Using the inbuilt 'Sweave-test-1.Rnw' file as an example:

> testfile <- file.path(.path.package("tools"),
"Sweave", "Sweave-test-1.Rnw")

Sweave - documenting a long function
Hi,
I would like to use Sweave to document a long function.
Is it possible to split the function's code into chunks
such that Sweave will accept each chunk without complaining.
I have tried various approaches without sucess
but I feel sure that someone has done this already.
Here is one attempt

R: R: Hidden Markov Models
Thank you for your prompt answer.
The breathing signal observations are the amplitude values as a function of time and phase.
According to our model the hidden states are the different breathing types.
Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type,
for many consecutive cycles. therefore dwelling in the same hidden state.

Custom Alloca implementation
---Adding llvm-dev list to CC---
Hi Alberto,
Thanks for your prompt reply. Actually, I need this information(about total
allocation size and object structure) on runtime, so that is why I was
planning to encode this info and store it in the memory itself.

Interpreter crash due to an "Unknown constant pointer type!"
David,
sorry for this email but I noticed I made a mistake in the previous one. So
I managed to compile llvm Debug with asserts release. I have used the
following commands:

Interpreter crash due to an "Unknown constant pointer type!"

> Hey Lang - does any of this look familiar to you?
I'm afraid not: I know nothing about the interpreter. As far as I'm aware
it's essentially abandonware.
Alberto: The usual recommendation in these circumstances is to use a JIT
class instead of the interpreter. You're using -force-interpreter though,
so I assume you really want to use the interpreter for your use case?

Interpreter improvement
Hi,
I my case I needed to trace the execution of a specific .ll file. I wanted
to know when a store and load instruction were executed. Maybe extending
the Interpreter class was not the best option so I'm happy to hear
suggestions.
As a curiosity, why do you think that class should be rewritten?
Thanks

How to add instructions to a Module at runtime?
Hi David,
Thanks for your answer. Just to clarify, I would like to create 2 3
instructions put them in a function and execute them. Do you still think
the JIT would be the best option?

Efficient way to identify an instruction
Hi Alberto,
I have not used this myself, but I think you should be able to visit your Instruction ‘users()’. I think the name this function was given is a bit confusing, but this returns an iterator range you can iterate through to find instructions that depend on a given one.
Similarly, you have the function ‘uses()’ that can be used to traverse down the DAG when instructions are still on SSA

Standard way to remove llvm intrinsics
Hi Eric,
Currently I'm mainly playing with interpreter and trying to understand how
it exactly works. I have noticed that lli complains when llvm.dbg.value is
encounter that why I wanted to remove it. Additionally, I would like to
understand that performances with and without intrinsics and the impact
they have on the interpreter in general.
Thanks
