segments within a lattice graph
Hi,
I would like to use the segments command
within a lattice graph.
Is this allowed in R in the same way as in SPlus?
If not, what is the alternative?
For example, the following produces vertical
line segments between points in SPlus
but in R the line segments are not shown.
(I want to replicate in R what I see in SPlus.)
What is my mistake?

frechet distance
Hi, is there any package (or source code snippet) that will evaluate the
Frechet distance for curves represented as sets of points?
Searching around only threw up references to a Frechet distribution.
Thanks,

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

Three Parameter FRECHET Distribution
Dear R Helpers
Which package is available for estimatine the parameters of three parameter FRECHET distribution. Also, how to generate the random numbers for Frechet using these three estimated parameters.

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

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.

Fit Frechet Distribution
hello everybody
i want to use the maximum likelihood method to estimate FRECHET parameters of
my sample data.
Should it work with fitdistr in the package MASS?
I only find how to do it for GEV, Gumbel, and almost all other distributions,
but FRECHET?
I would be very happy if somebody can tell me how to do fit the FRECHET
distribution!
Thanks

Distribution transformations
Dear R-Users,
I have a question that bothers me in the last few days. It is supposed to be easy but I can't come up with a solution.
Are there any functions in R dealing with transforming empirical and parametric distributions? I have two data sets of observed variables that I want to transform to Frechet and Uniform distribution.
I would appreciate if someone could inform me about

How to plot countours with fixted densities?
Hello,
I used the following codes to generate bivariate normal dependence structure with unit Frechet margins.
Sigma <- matrix(c(1,.5*sqrt(1),.5*sqrt(1),1),2,2) # generate
y <- mvrnorm(Nsam, c(0,0), Sigma) # random
v <- cbind(pnorm(y[,1],mean = 0, sd = 1), pnorm(y[,2],mean = 0, sd = 1))
z <- cbind(-1/log(v[,1]),-1/log(v[,2]))

Non-installation of Samba

I am attempting install of samba 2.2.7 on a Sequent (IBM) Dynix 4.4.6

I ran "./configure" which generated a number of messages before failing as

Identifying peaks (or offsets) in a time series
Dear R-users,
We are monitoring the activity of animals during a few days period. The
data from each animal (crossing of infra-red beam) are collected as a
time series (in 30 min bins). An example is attached below.

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.
Regards,

clearing some part of a graph
Hi R lovers
2 questions:
1) I'd like to know how to clean the title, the sub title or the labels of
a graph. I know how to redefine it with the function title() but it
overwrites the previous title and do not replace it
2) How could I clear a whole plot (for example in a multiple figure
environment)
thanks for your help

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

Fit Frechet Distribution
Hi everyone,
is there a function to fit a frechet distribution? The only thing I
found is gev.fit from ismev which fits a generalized extreme value
distribution (if shape>1 => Frechet) . Is there a function to only fit
a frechet?
Thank you
Benjamin
