help for memory problem with 64-bit machines
Hello,
I would appreciate *any* ideas on this problem. I'm the maintainer of a
package ("subselect"), which on CRAN's Daily Package Checks is OK on all
flavours of R, except r-devel Linux x86_64, where there is a "memory not
mapped" segfault with the very first example that is tried out (output below).
Additionally, a user with an AMD64 machine has just reported a

New version of Subselect package
Version 0.9-99 of package "subselect" is now on CRAN.
The subselect package has functions that search for k-variable subsets
of a p-variable (p>k) data set that are optimal under some
criterion. Search algorithms include a full search algorithm "leaps",
based on Furnival and Wilson's leaps and bounds algorithm, and three
random search algorithms: a genetic algorithm

Package 'subselect' provides functions which assess the quality of
variable subsets as surrogates for a full data set, in an exploratory
data analysis, and search for subsets which are optimal under various
criteria.
As of version 0.7 a new function 'leaps' has been added. 'Leaps'

a problem loading package 'subselect'
Hi,
I downloaded the subselect package from CRAN and installed it in the
system wide R library path. During installation the package compiled the
fortran sources with no errors.
However, when loading the library gives me an error:
> library(subselect)
Error in dyn.load(x, as.logical(local), as.logical(now)) :

Eleaps in package subselect crashes when using include arguement
I'm using eleaps to build a forward selection algorithm iteratively, but
the program unexpectedly crashes. In fact, it completely closes my session
in RStudio. The first 39 steps work fine, but on the 40th step, it
unexpectedly stops with no errors. I've isolated the error to the code
snippit below. There are 39 predictors, and I'm searching for the 40th

hi all
is there a package that undertakes subset selection but BASED ON AIC or
any other information criteria.
i've seen the "subselect" and the "leaps" package but i have not played

eager associations and limit/offset
Hi,
currently the eager association loading via ":include" does not work
when a has-many or habtm association is combined with offset/limit
(which is required for paginations). This is because in these cases, the
result set will contain more than one row per object, but limit/offset
works on row numbers.
I''ve developed a patch that makes this work by using 2 SQL statements

Problem saving logic regression result equation to disk file
I want to get some "simple" logic regression examples to work before
exploring a hard problem.
I can get results, but I'm having some problems using "cat" to save the
logic regression equation to a disk file.
Consider this:

subset selection for logistic regression
R-packages leaps and subselect implement various methods of selecting best or
good subsets of predictor variables for linear regression models, but they do
not seem to be applicable to logistic regression models.
Does anyone know of software for finding good subsets of predictor variables for
linear regression models?
Thanks.

problems with rexp ?
Does anyone know if R have any problems with the exponential random number
generation (function rexp)?
I comment it because I executed
data<-sort(rexp(100))
plot(data,dexp(data)/(1-pexp(data)),type="l")
and the graphic isn't constant.
(Note: exponential distribution have a constant hazard failure rate).
Thank you,

gam function & time trend splines
I've been doing a simple time-series analysis looking
at the relationship between daily pneumonia
hospitalizations and daily temperature. To mimic some
of the literature, I've been including a time-trend to
try to account for normal cyclical trends in
hospitalization. So I've been using a function that
looks something like this:

a correlation matrix subset where the subset avg is a maximum
Hello R group,
Given a correlation matrix, I would like to obtain the best subset of
pairs in the matrix of some size > n such that the mean of r for that
subset is a maximum compared to any other possible subset of size > n.
I've been looking at the deal and subselect packages but they don't seem
to do what I need. Does anyone have any suggestions?
Thanks in advance,

New package test results available
We've added a column at
http://cran.r-project.org/web/checks/check_summary.html
of test results using the Sun Studio compiler: it is intended that
these will be updated weekly.
The Sun Studio compiler is that used on Solaris: these runs were on
the Linux version. All the other platforms are using gcc 4, so this
provides an opportunity for checking for use of gcc-specific features

tapply syntax
Dear R-help members,
Apologies for the trouble.
I have a question :
Essentially, I have a dataset which stores genetic variations for individual
patients. Each individual patient can have more than one variation, and each
new record corresponds to a new variation (thus, both individual patients
and variations are non-unique).
So the dataset looks something like this ((letters = patients,
