Hello to all is there a function wich splits a data.frame (column1,column2,column3,....) into data1 <-(column1,column3....) #column2 = 1 data2 <-(column1,column3....) #column2 = 2 data3 <-(column1,column3....) #column2 = 3 ... Regards Knut

Hello everybody, I have experience coding with R, but am brand new to R Shiny. I am trying to produce an application that will allow users to upload their own dataset, select columns they want an ANOVA analysis run on, and generate graphs that will allow users to view their results. However, I am getting the following error: *"Argument is of length zero."* Being new to Shiny, I am

I''ve finally gotten lighttpd working for my production instance (SUSE 10.0 with SSL). (Had to install the fcgi dev toolkit, the SUSE 10 ruby-fcgi rpm, and the fcgi gem. I''m not positive all 3 were required, but that is what I did.) Now the devel instance of my app is broken. I''m not sure how to fix it. Previously I was using WEBrick for both devel and production.

I''ve just install Eclipse with RadRails for the first time. I''m trying to follow the very simple DemoAppPart1 at http://wiki.awebfactory.com.ar/awebfactory/published/DemoAppPart1 When I click on the DepotServer and try to start it WEBbrick is not starting. I can cd to the base directory and run script/server and it works. Any idea what I''m doing wrong? Thanks Greg

I''m really lost on this issue. Do I need to reinstall rails / gems? The rest of my rails setup seems to be working. I just can''t run dispatch.fcgi. (Details in original message below). I have no idea how to troubleshoot this. I''m not even positive it is supposed to be runnable from the command line. I found a troubleshooting guide that implied it was supposed to

Hello Thomas, Consider that the primary bottleneck may be tied to memory usage and the complexity of pivoting extremely large datasets into wide formats with tens of thousands of unique values per column. Extremely large expansions of columns inherently stress both memory and CPU, and splitting into 110k separate data frames before pivoting and combining them again is likely causing resource

All, I have a small Intranet app I''m trying to get ready for remote access. (I only have 15 or so users for now and I don''t plan to be adding very many more.). I have installed the login engine and it seems to be working as advertized. (Great job!) For my needs I don''t want random people to be able to register and get access to my app, but I will need to register

I have a small intranet app with only 20 or so users. I''m currently using lighttpd w/ssl for production and mongrel for dev. I don''t think Mongrel supports ssl, but what is the easiest front-end to put in front of it? Pound? Thanks Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century

Hi Thomas, Glad to hear the suggestion helped, and that switching to a `data.table` approach reduced the processing time and memory overhead?15 minutes for one of the smaller datasets is certainly better! Sounds like the adjustments you devised, especially keeping the multicore approach for `make_clean_names()` and ensuring that `ID_Key` values remain intact, were the missing components you

Hi Gregg. Just wanted to follow up on the solution you proposed. I had to make some adjustments to get exactly what I wanted, but it works, and takes about 15 minutes on our server configuration: temp <- ??????open_dataset( ????????????sources = input_files, ????????????format = 'csv', ????????????unify_schema = TRUE, ????????????col_types = schema( ????????????"ID_Key"

All, My initial list is rather busy. I would like to shorten the created_on and updated_on fields to just display the date, not the time. Best wold be a simple 12/28/05 type of presentation. I''ve found the format helpers in rdoc. (ie. distance_of_time_in_words_to_now ), but none seem to be what I''m looking for. How do I control the date format of a timestamp field? Thanks

About to try this implementation.

I am new to R, but have been using SAS for years. In this transition period, I am finding myself pulling my hair out to do some of the simplest things. An example of this is that I need to generate a new variable based on the outcome of several existing variables in a data row. In other words, if the variable in all three existing columns are "Yes", then then the new variable should

I''m a newbie. My first app is using a table called cases. With just "scaffold :case" I get the basic list to show up. I just did a "generate scaffold case case" (I think that is correct). Now when I try to list my cases, I''m getting a syntax error on all of the view source code that references "case". ie. <% for case in @cases %> Thanks

All, I know there are 3 or 4 search plugins out there. I''m trying to find one that will allow me to search associated fields. My database content is pretty small, so efficiently is not so critical. On the other hand I have ton of :belongs_to type fields, so I need something that works well with the Rails models. Any recommendations? == Example of what I need to work Assume I have a

All, I want to know in the Application.rb controller if I''m on the login screen. When I''m on the page I care about the controller variable is "#<ActiveRbac::UserController:0x408b3d6c>" So I want something like: if controller contains ActiveRbac::UserController What is the right syntax for the above? Thanks Greg -- Greg Freemyer The Norcross Group Forensics

hi all, i have a simple scatter plot, and i'd like to make it so the scatter plot colors are slightly transparent. i see in a previous post that someone mentioned the "alpha" parameter, but i am not sure how it can be used with the 'plot' function [*]. for example, suppose i have: plot(mydata$column1, mydata$column2, col="red", cex=1) i now want to make it so

I''m trying to work out how to use the functionality from a plugin in an engine. It sounds weird, but it''s actually not so strange. I assume I can''t just add a vendor directory to an Engine, so some strategy for getting the plugin in the lib folder is probably necessary (and then requiring the plugin, perhaps?). -- Yehuda Katz -- Posted via

I''m trying to write a test like the one at the bottom of page 148 in Agile Rails. I''m using rails 1.0 I''ve created the fixture correctly I''m pretty sure because the test database table is being populated per the fixture. I have what I think is a simple unit test: ========= require File.dirname(__FILE__) + ''/../test_helper'' class CaseTest

Thomas, I'm curious - what OS are you running this on, and how much memory does the computer have?? Let me know if that code worked out as I hoped. regards, gregg On Wednesday, December 11th, 2024 at 6:51 AM, Deramus, Thomas Patrick <tderamus at mgb.org> wrote: > About to try this implementation. > > As a follow-up, this is the exact error: > > Lost warning
