What are the features of R based Web Consoles? What are their advantages and disadvantages?

That's easy:
Rweb is pretty old, and a basic webinterface. The R FAQ lists more such webapps in its Section 4 on R and Web interfaces.
Webapps such as Rweb are for external third-parties, and mostly involve pre-canned code.
RStudio is new (and especially if running in web-mode on a server) a phenomenal new-school 'application as a webservice'. If running that way, or as a local app, it provides an IDE for R. That is different from a webapp.
IDEs such as Rstudio are for developers writing code. Theses IDEs are not facing unknown anonymous users.

I am new to business integration.
It is under my consideration that as a software engineer one's task is to design/deploy web services using an application server and some integration design tool and to provide mediation software modules to decouple existing web services.
The thing is I am not familiar with SOA philosophy and am still a bit lost in various documentation.
I understand the tools used are application servers(like WebSphere or Jboss) development environments (like Java EE Eclipse or IBM Integration Designer).
I need a concrete example from Alpha to Omega on how a SW engineer acts in deploying a business integration project.
E.g what kind of enterprise could one collaborate with and what kind of business logic has to implement...
I know my question is vague but I am starting from scratch and I need to understand essential concepts.
Any advice would be accepted as well.
Thank you!
An exceptionally broad question and myriad answers.
I suggest you start with this. It should provide a good begining understanding of SOA.

i have a general question. I want to develop a Web Application for business process modelling. The application was build using c# and WPF as Desktop Application Software and now i would like to develope it as Web Application. what technology should i choose?
I've tried to find it myself but there are many different opinions about that topic. Is there any general rule or methodology which can help me decide?
Your question is not quite constructive. You need to talk to some Architect to understand your business and the requirements to fill up the gaps of choosing a technology. It is quite vague to answer your question whether to choose ASP.NET webforms/MVC or probably a different platform than .NET to suit your needs.
On a general answer, if you are planning to port your whole application developed on desktop using WPF, you can consider porting to Silverlight which might cut down your cost to 90% (probably), where you will able to reuse all codes you have written so far. But that's totally your call and your business needs.

I am a student and I'm currently doing senior project. I'm required to work on the application control or application platform to let a group of programmer work together on a server with the security. I would like to know how a group of programmer work together on a server and how to work using visual studio 2010 on a server.
Thanks
First of all you have to use a version control system for your code such as SVN, which is one of the most popular.
There are also some other popular systems like GIT. You should try them both and see what fit your needs.
You'll probably want to create user accounts for each programmer on the server and allow them ssh access. Look into git for project version control.

What are the pros and cons of using MSI and MSP in using them for deployment. I was thinking of automating the deployment of my software using MSI and MSP.
I wanted to understand if there is any concerns. And also how feasible is it to use MSP for patch deployment
For MSI package advantages you can go through this thread:
What's the prime advantage to having an MSI installation package?
Regarding MSP patches, they were designed to be applied as patches. If you follow the patching rules, they work perfectly.

There are a number of commercial offerings that I've come across but nothing open-source.
I realise that you could do something simiilar with JUnit / JMeter but I'm looking for something a bit more specific.
What about clif
http://clif.ow2.org/
or jmeter
http://jmeter.apache.org/
I think there are others, but these two spring to mind.
You might want to have a look at Apache Jakarta Cactus
Jmeter + server logging + your brain.
Load testing is a very complex activity. You'll need to be able to simulate many contexts (e.g., IP, port) and divide the load generators on many machines. While doing that you'll need to monitor the server (Application under test).
As of today, there are several very good commercial tools that needs certain level of expertise to work with.
I don't think there is any serious open source load testing tool.
