Hi, When adding an index to another one using add_indexes I get duplicates even though I use the :key attribute. For example: def test_add_indexes_uniqueness index1 = Ferret::Index::Index.new(:key => :id) index2 = Ferret::Index::Index.new(:key => :id) # Add two items with same id index1 << {:id => 23, :data => "This is the data..."}

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

Hi, I am a Ph.D. student from Québec, Canada. I’m a beginner with R and Bioconductor. Until now the only experience I have is in analyzing microarray data using affy and limma packages. Now I am trying to analyze Rat Gene 10 st arrays and I would like to run RMA analysis and Smyth moderated t test on those arrays. Since no cdf official package is available for those arrays, after reading many

Hi, I'm trying to plot bar graphs with stacked columns marked with askterisks for certain columns, which follow certain criteria. I've gotten the stacked bar plots with Data set A (please refer to code below). However, I haven't figured how to put asterisks on columns based on some extra information (such as "used/unused") as in Data set B i.e. asterisks at the

Hi everyone, I have 2 environments (2 different R sessions) as described below: Session 1: Name of the environment: "CrlmmInfo" Objects in the environment: index1: logical index - length 238304 index2: logical index - length 238304 priors: list of 4 - (matrix 6x6, 2 vectors of length 6, vector of length 2) - all num params: list of 4: centers [238304 x 3 x

Hey, Thanks for your great inputs. While "index = apply(mat == 0, MARGIN = 1, any)" gives you an idea of the rows containing zero(s), "index<-data[!apply(data==0,MARGIN=1,any),]" does the actual job of removing the rows with zeros.

Hi All, I have a whole lot of *.raw files in my working folder and I am doing the same analysis on each of those and want to save all the results in a single file. I am making some mistake here and can't figure out how to solve it. Say, the *.raw files are ABCD.raw, EFGH.raw, IJKL.raw ... The files are of this format ID PHI?? aa1? aa2? aa3 .... 1??? 1???? 1.3?? 2.0?? 1.0 2??? 0????

Hi, I'm using "by" to summarize by multiple groups, and want to extract the returned into a pretty dataframe. I'm trying to find a simple way to name the rows of the data frame. I'd like it to be something like index1.val1.index2.val2 where the index1 and index2 are the names of the indices and the val1 & val2 are names of possible values of the index. (the

This is assuming that match() and unique() will never disagree on equality between 2 floating point values. I believe they share some code internally (same hashing routine?), so maybe it's reliable.

Buenas, He creado dos andamios para dos tablas a la que accedo por index1 e index2 respectivamente. En cada index puedo hacer las tareas de añadir, borrar, ver lineas... pero me gustaria saber como se hace una busqueda mas compleja...es decir si tengo una tabla Productos y otra tabla descripciones y quiero mostrar en los productos con sus descripciones... he intentado en el index1 acceder a la

Is there some way to have these two sets of URLs use totally different controllers and templates? categories/list categories/show/1 admin/categories/list admin/categories/edit/1 admin/categories/destroy/1 admin/categories/update/1 Besides, of course, using different controller names ;). The first URL is publicly accessible, while the second contains admin functions. Also, with the second,

Dear listers: As a part of a intermediate process, I need to use and modify a very big matrix (some 30000x30000) inside the body of a function. If the matrix is defined in the function, R shows a error message "Cannot allocate vector of size 6.7 Gb". But if I define the matrix before the function is called (as soon as the dimension can be calculated) R can allocate it. The problem is

This is a proposal to enhance TableGen's ability to analyze and manipulate DAGs. Hopefully this will allows more complex DAGs to be built in TableGen. 1. Add a new value suffix. value(index) The value must be a DAG. The index specifies the operator or an operand, whose value is produced. The index can be 0 produce the operator 1...n produce operand by

I''ve looked through the docs and the wiki and can''t figure out how to go about generating select options and the update function for an item that has a HABTM relationship. I have a ''parks'' table and the park model has a HABTM to the ''states'' table. On the park edit page, I''d like a multiple select box to appear with all states show,

I have a feeds controller which generates RSS and Atom pages. I put ''caches_page :show'' in it. The problem is that the pages are saved with an html extension. As a result, browsers display the cached feeds as HTML rather than XML, and feed validators complain. There''s an option to set ''Base.page_cache_extension'' globally, but I don''t want
