similar to: flash object not clearing?

Cheers, I''ve stumbled over a bug with 1.0 and ActiveRecord store for session while migrating from pstore sessions. I created the table with `rake create_sessions_table` and set `config.action_controller.session_store = :active_record_store` in environment.rb. Everything runs fine except that the flash messages will not be cleared. I get the same message everytime on everypage I

Hi I had a hard-to-find bug in some of my code the other day, which I eventually traced to my misusing of sweep(). I would expect sweep() to give me a warning if the elements don't recycle nicely, but X <- matrix(1:36,6,6) sweep(X,1,1:5,"+") [,1] [,2] [,3] [,4] [,5] [,6] [1,] 2 9 16 23 30 32 [2,] 4 11 18 25 27 34 [3,] 6 13 20 22

I am having a hard time understanding just what 'sweep' does. The documentation states: Return an array obtained from an input array by sweeping out a summary statistic. So what does it mean "weeping out a summary statistic"? Thank you. Kevin

Given a long zoo matrix, the goal is to "sweep" out a statistic from the entire length of the sequences. longzoomatrix<-zoo(matrix(rnorm(720),ncol=6),as.yearmon(outer(1900,seq(0,length=120)/12,"+"))) cnames<-c(12345,23456,34567,45678,56789,67890) colnames(longzoomatrix)<-cnames longzoomatrix[1:24,] 12345 23456 34567 45678

(Rails 1.1, Ruby 1.8.4) In the layout for one of my controllers, I have a tag to display a flash message (copied from AWDWR), like this: <div id="data"> <% if @flash[:notice] -%> <div id="notice"><%= @flash[:notice] %></div> <% end -%> <%= @content_for_layout %> </div> If the

Hi, I am fairly new to 'R' and would like advice on the following. I want to calculate a weekly average number of reports (e.g. of flu, norovirus) based on the same weeks for the last five years. I will then use this to plot a chart with 52 points for the average based on the last five years; another line will then plot the current year, enabling a comparison of current weekly counts

there are really two related problems here I have a 2D matrix A <- matrix(1:100,nrow=20,ncol =5) S <- matrix(1:10,nrow=2,ncol =5) #I want to subtract S from A. so that S would be subtracted from the first 2 rows of #A, then the next two rows and so on. #I have a the same problem with a 3D array # where I want to subtract Q for every layer (1-10) in Z # I thought I solved this one

Dear R users, When dumping an R matrix object into a file -- typically via the 'write.table' function -- the 'eol' option can be used to specify the end-of-line character(s) which should appear at the end of each row. However the argument to 'eol' seems to be restricted to have length 1, whereas ideally I would like different rows to be written to file each with its own

Hi Shakeel, Assuming that you are starting with a bunch of dates: # make a vector of character strings that can be converted to dates rep_dates<-paste(sample(1:30,500,TRUE),sample(1:12,500,TRUE), sample(2013:2017,500,TRUE),sep="/") # if this isn't your format, change it date_format<-"%d/%m/%Y" # create a data frame with a column of dates

When I use stylesheet_link_tag, the results come back with a timestamp ID, like this: <link href="/stylesheets/style.css?1154009736" media="screen" rel="Stylesheet" type="text/css" /> I don''t want the query string and ID on the end, but I can''t see how to disable this in the docs. How do I do this? thanks, jeff -- Posted via

I''m using a cache sweeper class [1] to take care of some pretty complex sweeping. However, there is a problem with the current implementation. Namely, the sweeper gets called only when an action named in cache_sweeper is called using GET. As many methods where sweeper would be useful are using postback to send the form to the same action, this causes the cache to get swept when

Hi, this is a problem that occurs in the presence of two libraries (limma, xlsx) and leads to a crash of R. The problematic code is the wrong application of sweep or the product ("*") function on an LIMMA MAList object. To my knowledge, limma does not define a "*" method for MAList objects. If only LIMMA is loaded but not package xlsx, the code does not crash but rather

Dear Hilmar Perhaps this gives an indication of why the infinite recursion happens: ## after calling `*` on ma and a matrix: > showMethods(classes=class(ma), includeDefs=TRUE, inherited = TRUE) Function: * (package base) e1="FOOCLASS", e2="matrix" (inherited from: e1="vector", e2="structure") (definition from function "Ops")

My code that acts if a session has timed out looks like this: reset_session session[:expires_at] = nil # TODO - This flash is never shown, because we redirect maybe? flash[:error] = ''Your session has timed out, please login to continue.'' # An attempt to make flash stick around, not working flash.keep redirect_to :controller => ''security'',

Submitted for perusal, comment, improvements, and/or critique. The presentation is in 3 sections: motivation, code, and comment. Motivation: As a new-comer to R from matrix oriented Gauss and Mata, I miss the tools for using a vector (and operator) to ‘sweep’ across a matrix. Here is how these work. If M is I rows by J columns, then one entry corresponding to

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

Interrogating some (of my own) code in another package. >norm.meth <- getMethod("normalize", "MatrixLike") >message("str(norm.meth)") >str(norm.meth) >message("show(norm.meth at .Data)") >show(norm.meth at .Data) Last show() displays this: function (object, ...) { .local <- function (object, method = c("median",

I'm attempting to reflect the information for use with corresponding fields in GUI (in a different package), to provide default values, argname as key for UI label lookups, etc. So I want something much more like the formals of the implementation: { "object", "method": c("median", "vs", "tukey"),
