I am planning to run Monte Carlo simulations in an R environment (Windows 7). However I need to use old legacy statistical packages that are no longer executable in Windows 7, although I am aware that there are emulation solutions (Like VMWare) available. In addition I need to integrate these packages in a seamless workflow so that simulated data from R functions is pushed on the old package, processed, and pulled back for further analysis in R again.
I am aware that there are open source workflow tools (such as KNIME) that can integrate different software packages, but my internet searches tend to be swamped with references to WorkFlow Management software business applications that are irrelevant to me.
Is KNIME Analytics a suitable solution given my legacy software problem, and if not what workflow tool would you suggest?
Kind regards,
Giulio Flore

I wrote a simple R program and want to share it with my office. Most people in my office are not familiar with R and I imagine it could be kind of confusing for them to install R and all the required packages.
Is there an easy way I can share an R script that can take user inputs & share output that doesn't require R installation on the user's end? I'm thinking something like Shiny, but for desktop use.
Your users can run R in an R jupyter notebook that you have set up in advance on some server. Then it's not a "desktop app" per se but it's going to look like it is running in their local web browser like Firefox or Chrome etc. Sharing R code you wrote will work excellently this way.

I am a newbie in Machine learning and Statistics. As I used opencv for my project(which I used in visual studio) and wanted to perform basis persuit operation, which is difficult to perform. So, I searched and took opinions of expert to get efficient programming library based on c++(I am from electronics background and c++ knowledge is more than sufficient).I have got information that you can build R programs on eclipse>
Can you please suggest me some references for running R on visual studio??
Does Rcpp runs on Visual studio?
Here is answer with source:
2.9 Can I use Rcpp with Visual Studio ?
Not a chance.
And that is not because we are meanies but because R and Visual Studio simply
do not get along. As Rcpp is all about
extending R with C++ interfaces, we are bound by the available toolchain.
And R simply does not compile with Visual Studio.

I am recently starting R programming and I find it very interesting.
I found the package rattle for R which can handle statistical models without coding.
Also rapidminer can be integrated with R.
I am not advance coder. Is it possible to use tools like rattle and rapidminer with R to perform all tasks which SPSS can do?
Cheers.
I recently started using R and found the Rattle GUI interface a good gateway to coding in R. You can do much of what you want to do, load data, visualise, clean, run models etc.
The best part is Rattle saves all the underlying R code you are are utilising in the 'Log' tab of the GUI. That way you can learn basic commands you need to learn and save the log as a starting point for building your own R scripts.
To install:
install.packages("rattle", repos="http://rattle.togaware.com", type="source")
Edit: Once installed, to run the GUI:
library("rattle")
rattle()
The website for Rattle.
For other options have a look here.

I am trying to visualize a VXML file, and have been searching for hours for a free and if possible open-source application, that would run on Windows, despite my intensive search I could not find any application.
Does anyone know a VXML visualizer?
Take a look at the Eclipse Voice Tools Project. This open source tool lets you visually develop a voice application that runs on any VoiceXML 2.1 compatible system. The only problem with this tool, and any other VoiceXML tool, is they store the information as meta-data that is translated to VoiceXML either at deployment or at run-time. This will lock you into a tool vendor since it will not be portable from one tool to another. There are not any tools, open source or commercial, that can take straight VoiceXML and visually represent a higher level abstraction of the voice application.

I was wondering if there are any automated tools for displaying a database schema diagrammatically?
My artistic side fails me and it would be nice to open my discussion with a diagram which doesn't scream ugly.
Many thanks,
Gav
Sure, there are plenty of tools, especially commercial ones such as DeZign. Are you looking for free SW, or could you afford a few hundred dollars for a license?
Edit: since you've clarified you have no funding for such tools, let me point out that there are free ("as in, free beer";-) possibilities, too -- for example, there is supposed to be a "Free Edition" of the commercial package DBVisualizer (the site of the firm producing that package talks repeatedly about this free edition but appears to only offer links to the evaluation version, for which you'd have to purchase a license after a while; however, with a web search I see several links to free-edition downloads, maybe a few versions back). I have no experience with this package (in either edition) but it may be worth your while to try!
