Does anyone know of a free entity relationship diagram software? My pencil and paper diagrams are getting rather elaborate and overlapping and hard to update. I used to use WO Modeler and it had an Entity Relationship Diagram tool which auto synched with the DB and drew the relationships and allowed you to see the model files in a visual way. Cayenne was a off shoot of that ; if anyone knows

Did I see some code posted here that would create a graphical representation of a database relationships using the graphviz utilities? -- Posted via http://www.ruby-forum.com/.

I've been using sna to work with some networks, and am trying to visualize them easily. My networks are hierarchical (food webs). All of the layout engines I've tried with gplot don't seem to plot hierarchical networks, as one would using dot from graphviz. While I could do all of this by outputting to dotfiles and running it through graphviz, the graphics I get from R are much

hi, I plot path diagrams with the path.diagram() function of the sem package in combination with the graphviz application. Now I want the graphviz code for a path-plot with the actual standardized coefficients on the arrows (not the names). I tried to add edge.labels="values" as an argument to path.diagram() but it's just ignored. can anyone help me on that? p.s.;

Dear R help I have conducted a fa() analysis, and I want to use fa.diagram to assess the extent to which the 11 latent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a

So, Anyone playing with the graph files yet? Just wondering if anyone has discovered a really good set of parameters to pass to dot to get the best looking graphs (OmniGraffle looks nice but I don''t want to pay for anything and want a way to generate graphics from the command-line). -- DK

I did a simple path analysis and tried to draw the path diagram. I used 'path.diagram' in sem package and produced a graph using dotty in graphviz; however, I don't know how to produce a graph from R directly. In the sem package manual John mentioned that "to obtain graphics output directly, the dot program must be on the system search path". Does anyone know how to set it

Hi, Given the convention of fat models to handle business logic, is there a point where you might be justified in using a separate plain ruby object(s) to orchestrate certain business logic interactions, essentially a middle layer between your controllers and models for high level functions? If you look at the InventoryTransaction model below you will see the sort of methods I mean. In this case

I am trying to use puppetlabs apache module on CentOS to install mod php package. class {''apache::mod::php'': } It returns error "Error: Could not find dependency Package[httpd] for A2mod[php5]". I am using Puppet 3.1 version. Do I need to call class{''apache'': } explicitly to get mod-php install working? If I try that as follows then it

Hi all, One of the major new features in the upcoming release is that Puppet now uses a graph library internally to handle resource relationships. The big benefit to all of you is that you can use this library to turn these graphs into images. The trick, right now, is adding --graph when you run puppetd. This creates .dot files, which can then be interpreted by the

Hello, I finally run my measurement model in sem - successfully. Now, I am trying to print out the path diagram that is based on the results - but for some reason it's not working. Below is my script - but the problem is probably in my very last line: # ANALYSIS OF ANXIETY, DEPRESSION, AND FEAR - LISREL P.31 library(sem) # Creating the ANXIETY, DEPRESSION, AND FEAR intercorrelation matrix

Hi, I am trying to convince aptitude update to run only when a file changes in /etc/apt/sources.list.d: exec { <snip> "aptitude-update": command => "/usr/bin/aptitude update", subscribe => "$basedir/sources.list.d", refreshonly => true; } File { owner => ''root'', group =>

Hi, thanks for reading. Till now, I''ve used railroad to visualize my models. But as far as I can see, there''s no possibility to add information about the model class methods. Methods are only added to a diagram, if you visualize your controllers. Is there a way to change this behavior? I''ve looked out for something else and found ''ruby-uml'', seems to

Thought some of you guys might like to know that that it looks like the BBC are trialing Rails.

All, This is probably a bit more of a mac question, but here goes. (Admission: I posted this to ruby-talk as well....) I am trying to use rdoc -d to generate class diagrams on a mac running Tiger (OS X 10.4) for a rails app. I managed to get dot installed, but now am running into problems with dot looking for libraries that either do not exist or are apparently in the wrong place. I probably made

Hi, since rails 2.2 doesn''t work with gettext anymore I decided to use a gettext dummy method until the gettext team relases a working version for rails 2.2. My application doesn''t need any i18n support right now and this way i figured it would be very easy to integrate gettext later. Just setup the plugin and go. So I need a method called _ which is available in alle models,

Hi all, I am trying to compile Rgraphiz on Windows 7 64bit with R-2.13.0. I have installed Rtools213.exe from [1]. The 64bit packages in [2] provided me with the 64 bit version of graphviz. After intalling the binary version Rgraphviz 1.30 (in 32bit) it complains (as expected) that: > library(Rgraphviz) Error: package 'Rgraphviz' is not installed for 'arch=x64' I

I have this challenge of converting a bit of html into an image file and then shrinking it into a thumbnail. The shrinking part shouldn''t be too bad, but what advice can you give on converting the html to the image? My thinking is that I will need to convert it to postscript or latex and then convert it to an image from there. Is there an easier / better approach? Michael
