Hello I have a question. I made an r-script and did a few commands needed to make some new variables. They all work out well, and when I run the commands, the new variables appear in the dataset. I can also work with these new variables to make other new variables from them. Also, when I use summary(dataset), those new variables appear in the summary of the dataset. But, when I do summary(new

Hi Hannah, Using the same code I sent before, you can append the partner codes to the household code. I apologize, but I don't know how to use the dplyr/tidyr/... stuff so this is written in straight R code using logic statements. ipumsi_00008_dta<- read.table( text="country year sample serial hhwt pernum perwt resident sploc sprule 204 2013 204201301 4000 10 1 10 1 5 2 204 2013

I''m hoping there''s an easy way to do this.  I''m trying to read options from a database, and insert them into form tags.  So for example, In the Database Table: options size: 300 type: text_field maxsize: 300 and I want to create a text_field form tag, with all the appropriate options, is there an easy way to do this, other than having the code output the HTML

Hey all, Ok this is probably a newb question, but I haven''t been programming with MVC for very long, and I''ve been wondering what the general opinion is, or best practices, for making a new controller. Like what cases would you need a new controller for and what cases can you just put everything into one controller? Thanks in advance, Randal -- Posted via

Noob Question 31,265,232 if I''m searching on an object, say order, that has many "order_lines" and I want to display order lines by Quantity ( an attribute of the order_lines ) descending how could I do that without having to do a find() with :order, but something like; Order.order_lines.each do |ol| <!-- code to diplay the line --> how can I determine the field

i have this model: class LineItem < ActiveRecord::Base belongs_to :quote end in the console: >>l = LineItem.create ActiveRecord::StatementInvalid: Mysql::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' , , , )'' at line 1: INSERT INTO line_items (`qty`, `quote_id`,

any suggestions on why I am gaining this error.

I''m getting errors whenever the user chooses, for example, April 31st ( since there is no 31st in April, navicat freaks out ), there MUST be a method that ruby has that would allow me to validate a date before I submit to navicat. I haven''t been able to find anything online about it either, it''s probably something simple, I just can''t figure it out. Thanks

Hey, probably an easy question but, I''m trying to get a method to run "before_destory" for a model, and I want the method to throw an error, and not delete the object from the database, if a certain condition is held Obviously, I can just raise an error and rescue it... but for some reason I can''t get <% error_messages_for ''model" %> to catch

I was wondering, is it better to maintain one large index or several smaller indexes? I am allowing users to upload files whose corresponding data is subsequently parsed and indexed. The problem is that each of these documents has different fields (which the user defines) and this makes searching and displaying search results slightly difficult. I tried to attach a unique ID to each file

I don''t even know what its called really, so its hard to search for. Here''s an example. They do this on MOG.com: There''s one text field visible. You type in a band name. Another text field appears. It auto completes album names based on the band name you chose in the first field. What is this type of thing called? Where is some source code I could look at? any

I have a small public IP block (/29) I'd like to populate with VM's from a single physical box running CentOS/5. I'd like to get some thoughts on the best way to setup networking to support this. I'm OK with setting up the virtual hosts. Any advice would be appreciated. TIA...

System: Gentoo Linux, fully updated (8/19/2006), Kernel 2.6.17.9 stock kernel, samba-3.0.22-r3 (have also tried samba-3.0.23b), 1Gb Ethernet. (thoughout). Problem: Very poor performance when copying files to or from the client, (ie 2000kb or lower on writes, 5000kb or lower on reads). Detailed Problem: If I use SCP from the same source to the same target (including drives), the speed of the

I have a Solaris system with Samba on it, along with two PC's a windows 2000 and XP. Shares were setup via SWAT. A user can access the shares on the 2000 machine after putting in login credentials when browsing through windows explorer. However, when trying to login the same share through XP the user gets "network connection has been lost." Although the XP machine can and stays

I've been able to successfully stream using Icecast with Darkice on my Debian box. I want to be able to stream multiple live streams from the same box using different sound cards (Basically, we have groups that will be using different TV channels and want to be able to stream the audio to the user's pc's for the proper channels they are viewing). Has anyone tried to do this?

Hi, I'm looking to implement a regression with mixed terms. I have 2 biological endpoints for a dataset of n=77, one linearly related and the other fits a spline. I want to combine these two terms in a linear regression for prediction, then apply the model to a test set. this works fine, good r2 and I've graphed the spline. m1<-lm(y~x1,data=train) m2<-smooth.spline(x2,y); (spl)

I got 2 cards working, and will need to add another 2 cards shortly. I hadn't thought about the matter-it's something I can try to play with later. What you've done here is awesome, where did you come across a system that could house 11 pci cards? ______________________________________________ Andrew Wehner Chatham Financial - Kennett Square T: 484.731.0029 -----Original
