Problem with Princurve
Hey all,
I can't seem to get the princurve package to produce correct results, even
in the simplest cases. For example, if you just generate a 1 period
noiseless sine wave, and ask for the principal curve and plot, the returned
curve is clearly wrong (doesn't follow the sine wave). Here's my code:
library(princurve)
x <- runif(1000,0,2*pi); x <- cbind(x/(2*pi), sin(x))

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

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:

Error in dyn.load(x, as.logical(local), as.logical(now)) :

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

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.

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,

Which non-parametric regression would allow fitting this type of data? (example given).
Hi,
I'm wondering which function would allow fitting this type of data:
tmp=rnorm(2000)
X.1 = 5+tmp
Y.1 = 5+ (5*tmp+rnorm(2000))
tmp=rnorm(100)
X.2 = 9+tmp
Y.2 = 40+ (1.5*tmp+rnorm(100))
X.3 = 7+ 0.5*runif(500)
Y.3 = 15+20*runif(500)
X = c(X.1,X.2,X.3)
Y = c(Y.1,Y.2,Y.3)

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,

Hi,
I've run into a bit of a problem with using the RMySQL library. I've
been attempting to create a temporary table in a MySQL database and then
perform a SELECT with a WHEREs clause on the table. In effect perform a
SELECT with a subSELECT.
The problem is that it never seems to be able to find the table after I
create it. I've been using the dbSendQuery method to create the table

In a find, can''t you use both :include and :limit ?
I''m trying to do a find that includes a join. It has to be a find
