I understand sweave or R2html could be a solution.
but please show me their applications in a large business setting. On
the contrary, I can give you many such cases using SAS.

For your 1st question, you can write query against the tables in DB using RODBC.
Being a SAS programmer, I have to say that reporting function of R is
not as good as that of SAS.

Hello:
I am studying the effect of schools on student achievement growth over
time. School effect is random. The effects of schools in prior years
are assumed to be persistent till the current year. Thus, the total
school effect in the second year is like J=J2+J1. Does anyone know how
to model this
Dear Adrian and Ian (and r-helpers),
I encountered a curious result in developing an example using the bicreg
function in the BMA package: I noticed that pairs of models with equal R^2
and equal numbers of predictors had nevertheless different BIC values.
Looking at the bicreg function, the defini

How to force some AR coefficients to be ZERO and only allow the function
"ar" in R to change the other coefficients?
Thanks a lot!

Hello everyone,
I would highly appreciate your assistance with the following:
I would like to add a line to the coherency plot of a multivariate time
series, denoting the critical value above which the null hypothesis of
having no coherency between the two series may be rejected.
Is there a mecha

I think you have to supply some details for anyone to be able to
answer. At least what you did (the code), what you got (the results)
and what you expected to get.

I am sorry. It was my fault. My example is wrong. I need also rearrange a
validation data set too.
But I have a sligthy different results with my real data. Where can the
problem be?

Hello useRs,
I am new user to R and also statistics. Why predicted results in this example
are different? Is the order of variables in X matrix important?

Hi useRs,
I have been running a regression of the following kind:

The minimum you need is to have a single file, DESCRIPTION, plus
R and man directories/folders which contain your .R and .Rd
files respectively. A package need not use C and I suspect most
don't.

Hi,
Just a silly question about R source package:
I downloaded some source package of R and found there are some source codes
written in C, is this true for all the R packages? but it seems that not all
the functions described in the package are contained in the source package
written in C.
Thank you both very much.

I don't think any of those cover such models, which are not GLMs.
One can of course run anything in R:
Evelyn Hall: I would like to know how (if) I can extract some of the
information from the summary of my nlme.
Simon Blomberg: This is R. There is no if. Only how.
