R is a command line based tool so I wasn’t that surprised when I started up the program and got a window with a command prompt: I downloaded the Mac version of R from the main project site. If you understand the problem well enough to explain it to a computer, then by definition you understand the problem. I’m a firm believer in letting machines do the grunt work of mathematics. I teach undergraduate math and occasionally blog about math education so math software is a particular interest of mine. I’ve been looking forward to this for some time. The source code is also freely available so you can compile it for any platform you like. R is free and available for Linux, Windows and Mac OS X. The name R is not just a play on the name S, but is also a tribute to the original developers, Robert Gentleman and Ross Ihaka, who were known at university as “R & R”. Currently it’s being maintained by the R Development Core Team, with contributors from all over the world. In the early 90’s, researchers at the University of Auckland, New Zealand developed a new version of S that they called R. But I really like ‘Bell Labs: Smart But Terse’.” “How about ‘Bell Labs: We Don’t Have Time For This’?” It was standard practice at the time to give programming languages single letter names. This was always annoying and occasionally painful, but there were no good alternatives until the mid-70’s, when researchers at Bell Labs developed the programming language ‘S’. (FORTRAN was my first programming language back in 1977. ![]() Assuming you didn’t have any typos, you got a printout of the results. You wrote your code, submitted it to the mainframe, which compiled and ran it. It wasn’t what you might call ‘interactive’. In the Olden Days (™), if you wanted a computer to do your math homework, you had to use FORTRAN. Once again, this is what you get when programmers write your sales materials – nothing but facts. a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities.”.graphical facilities for data analysis and display either on-screen or on hardcopy, and.a large, coherent, integrated collection of intermediate tools for data analysis,.a suite of operators for calculations on arrays, in particular matrices,.an effective data handling and storage facility,.It is free software released under the terms of the GNU General Public License.“ R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It is written in Common Lisp and runs on all POSIX platforms such as Mac OS X, Unix, BSD, and Linux as well as under Microsoft Windows. Maxima is a complete computer algebra system based on a 1982 version of Macsyma. ![]() Due to the open source nature of the software, some user contributions have been integrated into the main program. Scilab is available free of cost under an open source license. Scilab also includes a package called Scicos for modeling and simulation of explicit and implicit dynamical systems, including both continuous and discrete sub-systems.Īs the syntax of Scilab is similar to MATLAB, Scilab includes a source code translator for assisting the conversion of code from MATLAB to Scilab. ![]() The software can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations and numerical optimization. While the language provides simple matrix operations such as multiplication, the Scilab package also provides a library of high level operations such as correlation and complex multidimensional arithmetic. This allows users to rapidly construct models for a range of mathematical problems. By utilizing matrix based computation, dynamic typing and automatic memory management, many numerical problems may be expressed in a reduced number of code lines, as compared to similar solutions using traditional languages, such as Fortran, C or C++. The language provides an interpreted programming environment, with matrices as the main data type. Scilab is a high level, numerically oriented programming language. As part of the GNU Project, it is free software under the terms of the GNU General Public License. Octave is a computer program for performing numerical computations. FreeMat is available under the GPL license. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. ![]() FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. ![]()
