R – your tool for data analysis

R‬ is a language and environment for Statistical Computing and Graphics. R provides a free/open source, cross­-platform, object-oriented environment to perform data analysis and visualisation tasks. Strength of R lies in its vibrant community, robust package repository and strong graphics capabilities. ‪

R provides all necessary tools required for various stages of a data analysis project. It provides techniques for data acquisition and processing as well as for data analysis and visualisation. It ranges from accessing data in various formats (CSV, XML…) to all possible ways of data manipulation (tabulation, aggregation…)to rich support for graphics (histogram, box plot etc.) to statistical models (regression, ANOVA…).

It is not always necessary to use built-in and supported functions and packages. Depending on the requirements, one can also develop his/her own functions, scripts and packages.

Recently, CDAC Mumbai has announced a 3-day course on R entitled “Using R for Data Visualisation and Analytics”. This course is aimed to cover in detail the features of R related to data analysis and visualisation. More details can be accessed here.

Computer Training Program for Visually Challenged at CDAC, Kharghar, Navi Mumbai during July 23–August 4, 2012

About training:
In India, about 7-8 million people are suffering from full or partial visual impairment. Such people have to be provided with different kinds of support devices to access the world and to perform routine tasks like bill payments, banking transactions, reservations etc.. Now technology, either software-based or hardware-based, has made it possible for these people to access the world in their own way. But a large section of blind population is still away from advantages of modern assistive technologies. The main reasons for this gap are not only the lack of awareness about assistive technologies available and lack of hands-on practice to use it, but also the cost of technology. Free & Open Source Software (FOSS) tools/techniques play an important role in creating assistive technologies that are free-of-cost, available to all and easily maintainable for a large portion of population in a country like India. For visually challenged people, available computer based assistive technologies include screen magnifier, screen reader, braille display, digital book reader and many more. From all of these, screen reader is the most popular and potentially useful for such people to access the computer. A screen reader is a software application that just not reads the screen from top to bottom but also helps the user to navigate the interface by communicating the current position where s/he is, where to go next by giving appropriate feedback. This training program is intended to provide a learning platform for visually challenged persons to learn the basics of computer and the usage of screen reader. The training will include using desktop, text editor, command line, word processor, spreadsheet, playing multimedia, Internet browsing and mail client. Working of screen reader with other Indian languages will also be covered during the training program. More details about training program can be found at CDAC, Mumbai website (http://www.cdacmumbai.in). The GNU/Linux distribution for Visually Challenged developed by CDAC, Mumbai and FOSS based screen reader Orca will be used for training purposes.
Objectives of training program:
  • To create awareness about computer based assistive technologies available for visually challenged users.
  • To give hands-on training for basics of computer using screen reader.
