Hello, I found an interesting ER diagram on the "Module: ActiveRecord::Associations::ClassMethods" page of the Rails Framework Documentation : http://ar.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html At the beginning we can read ? Associations are a set of macro-like class methods for tying objects together through foreign keys. They express relationships like

Hi, I am running wine-0.9.56-1.fc7 on a Fedora 7 system. I installed Visio 5 (must be around 10 years old!). The Visio seems stable when running under wine, the graphics are good and I can save the vsd files under wine. Two small problems 1. Unable to save complex diagrams to jpg or gif. For example, there is an Office furniture template which includes walls, chairs and tables. The simple

I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/ but this deals with filling out forms. Is there a simpler example that just allows you to talk to itext , send it some plain text and get back a pdf and then send that pdf to the user as downloadable / renderable data? -- Posted via

Hello, I have been researching software for documenting pbx call flow paths and I was just wondering if anyone out there is using anything they have found particularly useful or cool. I am looking for something preferably visual that the average end user can follow. So far the best thing I have come up with is making a diagram with a decision tree in visio but its very time consuming to build

Hey Everyone - I was going to create a visio diagram outlining how my extensions will flow out. I was just wondering if anyone on the list may have an example they have already done up so I can get some ideas. Thanks ****************************************** Richard J.

Hello LARTC readers, I have completed a generic diagram of a linux traffic control scenario with HTB. I believe that the diagram is substantially accurate, although I''d like feedback from others. I will (eventually) be annotating the diagram in a separate HTML page, and would welcome any suggestions for annotations. Naturally, the annotation will have to cover some of the key

I created a 2d histogram using gplots' hist2d: hist2d(x,y, freq=TRUE, nbins=50, col = c("white",heat.colors(256))) rug(x, side=1) rug(y, side=2) box() Now I would like to reverse the Y-axis, tried to use ylim=rev(range(1:400)) but seems not to work. Any ideas? Ralf

Hi, I am a beginner with "R" and found a package "venn" to create a venn diagram. I tried this “venn” function to generate venn diagram, but i need *Percentage values* instead of counts(frequency) in the oval(circles) of Venn diagram. Output : http://r.789695.n4.nabble.com/file/n3664380/output.docx output.docx I have written have the code as below : # venn diagram for more

I had strange windowing behavior with R 9.1 on Windows XP when executing code from the diagram package. Perhaps it is even normal behavior that I don't understand as it was an unintentional discovery. I don't even know if it is a package issue or a windowing issue. Reproducing it. Execute the code fragment below from vignette(diagram) that uses par() to draw a four panel

Tom, I note that you use Visio for your network diagrams. Have you considered placing SVG source in CVS? I believe Visio can import/export SVG now. If you''re not using the newest version, I think the VDXtoSVG project can convert Visio 2002 VDX files to SVG. If you''re using a version older than that, I doubt an acceptable solution is achievable. VDX to SVG

Dear all, I am coming across a funny problem in taylor diagram. When I plot the diagram for given values of a variable some points are going outside the diagram. i have never seen such a diagram and hence cannot understand the reason for it. any help in resolving this issue would be greatly appreciated. the taylor diagrams are attached in this mail. thanks and regards Roopa -------------- next

Dear R-users I want to save a list with characters a point plot and a Venn diagram in a single pdf page. I am successful to do this when I use a character list and two point plots. However when I try to replace the first point plots with my Venn diagram (built with Vennerable package, compute.Venn() and plot.Venn()) the Venn plot will not position at the right place in the pdf. I guess there

Hi R- USER, I have been struggling to compute path analysis in R. I installed package "sem" and I tried to run the analysis but could not get a diagram. I have very big data set, here I just copied a sample of my data and I wanted to see how I can do the path analysis and get the patch diagram (with r2 in each path). I have two tables; 1: num. of species - which is the depended

Forgive me if I'm posting to the wrong place....It's my first time posting. Here's the situation: I'm using the sem package and making path diagrams using path.diagrams. Suppose I have the following code: #install.packages("ggm") require(ggm) cor = rcorr(7) nm = c("SOF", "IWF", "PWF", "FSC", "FSF", "EF",

Hi, I am using venn diagram function in AMDA to plot the venn diagram. But it seems in this function, it can only plot 3 or less vectors. Is there a way to plot the venn diagram with more than 3 vectors? Please help. Thanks. Z --------------------------------- [[alternative HTML version deleted]]

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, 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-list, I am trying to visualize where the dropout happens in our patient flow. We are currently using traditional flowcharts and it bothers me that I can't visualize both the percentage and the flow in one diagram. The other day I came across some interesting diagrams doing exactly what I wanted, they had both flow and percentages visualized on one diagram. Here is some nice examples
