Problem installing packages and weird R site behaviour
Hi,
I tried to install a package using the menu option and was presented a list
filled with NA's.
I then tried visiting the R site and each option on the side bar (eg. CRAN,
Search,FAQ) sends me to the address attached below (NB: I left off the h in
http).
The first problem seems to be related to the second.
Is anyone else experiencing this behaviour and how do I restore normal
behaviour?

Hexidecimal conversion
Help
I can produce the hexidecimal equivalent of a decimal number but I am having
a hard time reversing the operation. I'm good for hex representations to 159
and am close to extending to 2559. The archives are not clear on the
existence of a function for this task. Is there one?
Here is what I have got so far:

Error using newdata argument in survfit
Dear R-helpers,
To get curves for a pseudo cohort other than the one centered at the mean of
the covariates, I have been trying to use the newdata argument to survfit
with no success. Here is my model statement, the newdata and the ensuing
error. What am I doing wrong?

glm.poisson.disp versus glm.nb
Dear list,
This is a question about overdispersion and the ML estimates of the
parameters returned by the glm.poisson.disp (L. Scrucca) and glm.nb
(Venables and Ripley) functions. Both appear to assume a negative binomial
distribution for the response variable.

the R package - relation to R project?
I stumbled across this link and was wondering if this has any relation to
the R project.

reshape direction=wide
Hello
I am reshaping a data.frame bids --> reshaped as shown below.
I thought this should be possible with a single invocation of
reshape, but the only way I came up with is reshaping subsets for each
keyword and then joining them together. Does anyone have an idea how to
solve this in a more elegant way? Efficiency is a concern as the datasets
are very large.
Is there a way to specify

problem with temp dir (PR#3272)
Hi,
I recently installed R on a Windows 95 machine. Everything went well untill
I tried to run the program. I get the R console and a message "fatal error
can't mkdir R_TempDir". The R-help archive has a report of a similar problem
but the instructions for repair seem to assume that the R console is
available (the program closes after the error). An installation on an

identify() and controlling label size
I thought this was going to be easy ...
Can the label size of identify() be controlled by setting par(cex.*) because
I'm having no luck? My only recourse is to save the index and position of
the labels from identify() and use text() to replot them.
Regards

RODBC and Table views
This question relates to the use of the RODBC package for retrieving data
from a MS Access database. It is quite easy to retrieve data sitting in
tables but is it possible to select from views based on these tables? The
archives do not touch on this point.
sqlTables() lets me see tables and views but only the tables yield data. Do
I need to recreate these views on the R side of the connection?

Estimate of baseline hazard in survival
Dear All,
I'm having just a little terminology problem, relating the language used in
the Hosmer and Lemeshow text on Applied Survival Analysis to that of the
help that comes with the survival package.
I am trying to back out the values for the baseline hazard, h_o(t_i), for
each event time or observation time.
Now survfit(fit)$surv gives me the value of the survival function,

Pearson correlation coefficient matrix with permutation test
Hello,
I found an interesting program on Pierre Legendre's webpage:
http://www.bio.umontreal.ca/casgrain/en/labo/corr_permute.html
With this program one can compute a "Pearson correlation coefficient matrix with permutation test".
This is exactly what I need as an R-package because so far I have only analyzed my data with the function cor(). However, I need additional

Hi
I'd like to know if the R can do the DCCA? Because I can't find the package about
the DCCA in R. If it can not, please introduce a free software to me, which you
think can easily do the work , thanks!

php3 module and security
Hi,
When php3 module is compiled in apache, files in any directory will
be interpreted by the parser and executed. This is a security breach.
There is a way to correct this? Any comments?
Thanks,

I need to evaluate a series expansion using Legendre polynomials.

Double integration - Gauss Quadrature
Hi,
I would like to solve a double integral of the form
\int_0^1 \int_0^1 x*y dx dy
using Gauss Quadrature.
I know that I can use R's integrate function to calculate it:
integrate(function(y) {
sapply(y, function(y) {
integrate(function(x) x*y, 0, 1)$value
})
}, 0, 1)
but I would like to use Gauss Quadrature to do it.
I have written the following code (using R's statmod package)

assistance with RDAtest beta version application
Pierre Legendre has developed a beta version of a new redundancy analysis package called RdaTest that is available on his web page at the Universit® de Montréal. The test example that is included with the package is based on the example provided in his book (Numerical Ecology, Chapter 11 (Legendre & Legendre 1998))
