The R software is powerful but it takes a long time to learn to use it well. Howver, you can keep using your current software to access and manage data, then call R for just the things your current software doesnt do. This paper introduces the minimal amount of R commands you need to work this way. It also shows how to call R routines from many other packages including SAS, SPSS and JMP. Keywords.

R 1 is free, open source software that does statistics and graphics. You can download it from http www. Written by Robert Gentleman and Ross Ihaka, R is based upon the S language developed by John Chambers 2 and others at Bell Labs in the 1. It is a language that is optimized for writing analytic procedures, somewhat similar to SASIML, SPSS Matrix and Statas Mata. R also includes a rich array of pre written procedures, called functions. These functions are written in the R language, and in compiled languages such as C or FORTRAN 3. These functions are all open for you to study and, if you like, change. Both the quality of the R language and its openness to change has attracted many developers. These volunteers have written more than 5,0. R. Many data analysis packages can call i.

Other software typically uses a different language for each of those steps 4. R is free and powerful, but it does have limitations. While its language is powerful and consistent, it is considered by many to be harder to learn than other software. That is due to the fact that it has more types of data structures than just the data set, and its equivalent of a macro language and output management must be learned from the start.

Another factor that makes R somewhat harder to learn is that its help files are written for relatively advanced users. For example, the SAS help file for PROC PRINT provides a readily comprehensible description The PRINT procedure prints the observations in a SAS data set, using all or some of the variables. You can create a variety of reports ranging from a simple listing to a highly customized report that groups the data and calculates totals and subtotals for numeric variables. However, the help file for Rs equivalent print function provides a relatively cryptic description print prints its argument and returns it invisibly via invisiblex. It is a generic function which means that new printing methods can be easily added for new classes. That is much less clear. What is it printing and will the output be invisible Despite this complicated description, using the function to print your data set is as simple as entering, printmydata, or even simpler by merely entering, mydata. An important limitation of R is that it must hold all its data in your computers main memory. Although that allows it to analyze a few million records, it is not sufficient to handle the massive amounts of data that are becoming ever more popular. R users who analyze such very large data sets usually manage them in a database and then work on samples small enough to fit into memory. Since the field of statistics does a good job of generalizing the results obtained on relatively small samples to large populations, this is not as severe a limitation as it might first appear. Several projects are underway to overcome this memory limitation. A commercially available version of R has overcome this limitation for some of its functions 5. Installing RWhen you purchase commercial software, you receive it on DVDs, or you download it from the vendor. Every part of it you purchased arrived at once, and you install it all at once. Although commercial software is written in compiled languages such as C, FORTRAN and Java, the vendor compiles that source code and gives you only the binary version. R is available as a download from the Comprehensive R Archive Network, or CRAN, at http cran. Most people will want to get the binary version of R to install.

Thank you Ive been looking for a link to download SOFTWARE IBM SPSS Statistics 20 but link here redirects me to some adds. However, since R is open source software, you can download the C and FORTRAN source code version, and perhaps even change it to better meet your needs before you compile and install it. Since R has thousands of add on packages, they are not all included in the initial installation. There are several ways you can find useful R packages. If you are a SAS or SPSS user, you are probably already familiar with their add on products. I maintain a table of these add ons at http r. R packages that are roughly equivalent. Another good source to learn about packages is the Task Views page on CRAN http cran. Vanderbilt University maintains a similar site at http biostat. Detailed information about most R packages is available at http cran. The packages page on the main CRAN site is organized alphabetically, making it easy to find a package if you know its name. Another useful site with package information is, Crantastic at http crantastic. Created and maintained by Hadley Wickham and Bjrn Mland, the site allows R users to rate the packages and write brief reviews. There are repositories other than CRAN.

When using an Internet search engine such as Google, the letter R doesnt help narrow a search down very much, but adding R package including the quotes to any analytic term is likely to lead you to an R package that performs that analysis. Once you have found the package you need, you install it by starting R. You only need to do this once per version of R you install install. You. NeedR will ask you to choose a CRAN mirror, from a list of software repositories that are scattered around the world. When finished, the package is in your R library. Since Rs data must fit into your computers main memory, add on packages are not loaded automatically from your library. Every time you start R and want to use that package, you must load it using the following function call librarypackage.

NeedR is case sensitive, so be careful to respect every lower or uppercase letter in package names. Missing Data. While most commercial software packages use as much data as possible, R functions often yield only a missing result if it finds missing data. R does offer all the usual ways of dealing with missing values, including listwise, pairwise, mean substitution, multiple imputation and so on. However, if you are calling R from other software, you will probably prefer using that software to eliminate missing values. For example, if you had variables named x. SAS you could select a subset of complete observations to pass to R using data subset set all where nx. You could then send the subset to R for analysis. SPSS or Stata users could do the same type of selection by using the nvalid or rownonmiss functions, respectively. Selecting Variables. In most commercial software, you select variables using a fairly trivial process. For example, SAS uses the var statement in its various forms var q.
