search for: subselection

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)) : unable to load shared library

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

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

A new version (0.7.1) of package 'subselect' has been uploaded to CRAN. 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' performs a

Hi, I''ve read about this technique on the great Intraweb but can''t find it any more- hopefully someone can help or point me to a reference! I''d hate to reinvent the wheel if I can avoid it (and rediscover all the gotchas that someone has already found). I''m writing a rails app that I''d like to use to service a number of different websites out of

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 best. I've passed in a

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 around with them yet. thanx

Hey guys, I''m quite new in RoR, so please excuse me when I may ask weird questions. I am working on a database frontend. The layout looks mostly like a has_many bs b has_many cs c has_many ds and so on. Now I want to do some selection. Maybe I want to see all ds belonging to a specific b. I would like to do it like: http://my.host/bs/1/ds When I click around there (add new ds, show a d

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

Dear, I'm new to both Linux and R.

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. -Ben p.s., The leaps package references "Subset Selection

...efined for '[', these methods do hyperslab selection, however, currently I am limiting slab selection to contiguous blocks, i.e., things defined like: i:(i+k). I don't do any contiguity checking at this point, I just grab the max and min of the range and them potentially do an in-memory subselection which is what I am definitely trying to avoid. Besides using deparse, I can't see anyway to figure out that these things (i:(i+k) and c(i, i+1, ..., i+k)) are different. I have always liked how 1:10 was a valid expression in R (as opposed to python where it is not by itself.), however I'd...

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 Trying to cut down on queries with eager loading and noticed the following in development.log Load IDs For Limited Eager Loading - SELECT id ....etc Followed by Load Including Associations - SELECT table.id ... etc Is this common practice? What is limted eager loading? Cheers Mark -- Posted via http://www.ruby-forum.com/.
