graphic question
Hi,
I want to use R for some data mining project , and was wondering if it has
any intercative graphical features?
For example, is it possible to plot a histogram and be able to select a
specific point on it and have all the data about it? or select a specific
area in a curve and have all the data about it? or possibilities to zoom
out and in?
Thank you for your help,

T-Distribution
Dear sir,
I would ask if there are in R some code to generate a random sample
from a mvariate student distribution like that one wich generate the
multivariate normal one i mean( rmvnorm(n, mu, sigma)
Second question : if R can plot density 3Dcurve I don't mean de
histogram but de hole density function(normal for example).
I use a windows version of The R software
Thank you in advance

analysing data with case weights: rejoinder
Hello,
Based on replies (which I'm gratefull for) I guess the only solution
is to create a package, that will contain function to build
lm()-like linear models, and allow weighting cases (as I described
two days ago).
This would also alow buliding those models for data in aggregated
form without a need for using e.g. expand$grid().
Thank you again for replies.

iterative proportional fitting in R?
Hi,
We have some sample data from the US census, and we know the marginal
totals for the population. We need to make the population estimates add
up to the correct sums.
I have two questions:
Is there some package in R which does this adjustment, by any means?
Is there some more modern reference for this problem than Deming's 1943
monograph, ``Statistical Adjustment of Data''?

sub functions
Dear list,
how can I write the following two lines in one function:
> Pox2 <- ave(lsk0t50$Pox2, lsk0t50$ProfN, Fun=is.na(lsk0t50$Pox2))
> Pox2 <- data.frame(Pox2)
The following does not work:
> Pox2 <- data.frame(Pox2 <- ave(lsk0t50$Pox2, lsk0t50$ProfN,
Fun=is.na(lsk0t50$Pox2)))
> names(Pox2)

Indexing Elements of a Dataframe
Hello List-Members,
Let's say that I have the following code:
for (i in c(10, 20, 30)) {
for (j in c(200, 400, 600)) {
...
...
x <- "something"
* (code here)
}
}
* Now, x is some result that I want to put into a results "matrix" that
looks like this:
200 400 600
10
20
30

Non-english fonts in plots
Hello to all
I've got a question concerning use of fonts while making plots in R. I
wanted to know if it is possible for me to use polish letters in functions
like text() title() etc. Looked up characters, which can be obtained via
Hershey(), but there are none of them.
I made plots using postscript(), pdf() or png() device to export them to
MSWord or LaTeX.

analysis of data with observation weights
Dear R-users,
Recently I had to analyze a dataset from household survey. The sample design
ensured, that each household in the population has the same probability of being
sampled. However the data were gathered from only one adult individual in each
household, who was randomly choosen by an interviewer (via "Kish grid"). To
equalize the probabilities for each INDIVIDUAL a casewise
