[R] program and comment
Hi. I am a newbie to R. I need to do a courses projects with some manipulation lots of data record and some back-and-forth linear regression. I do not want to spend $100 for a SAS lincence, which professor used. So I decide to start to learn R to finish it. I am using R in Windows. I feel it is somehow works like mathemica. I try to write the work into a little program for future reference. (My data soon exceeds the workplace.) So that should be a script, right? Then I can load it in file/source R code. One thing puzzles me is that how to write comments in the script. I googled internet and the archive and did not find any clues. First, can anyone confirm that I took the correct approach for the problem? I understand R is quite different from program language like C/Pascal which I am familiar with and seems people write it with quite different style. Second, can anyone show me some idea about how to write the comment. Thanks. __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Comments can be added in R simply by starting a line with a # Greetz, Dirk -- Dirk De Becker Work: Kasteelpark Arenberg 30 3001 Heverlee phone: ++32(0)16/32.14.44 fax: ++32(0)16/32.85.90 Home: Waversebaan 90 3001 Heverlee phone: ++32(0)16/23.36.65 [EMAIL PROTECTED] mobile phone: ++32(0)498/51.19.86 Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

2006/4/26, Guojun Zhu [EMAIL PROTECTED]: Hi. I am a newbie to R. I need to do a courses *do* have a look at e.g.: - http://cran.r-project.org/manuals.html (An Introduction to R) - http://www.ms.unimelb.edu.au/~andrewpr/r-users/icebreakeR.pdf (contributed manual) - http://cran.r-project.org/doc/contrib/Short-refcard.pdf (reference-card) to search the archives you can use: - http://tolstoy.newcastle.edu.au/R/about.html - http://finzi.psych.upenn.edu/search.html I am using R in Windows. Have a look at Tinn-R (editor) like mathemica. I try to write the work into a little program for future reference. (My data soon exceeds the workplace.) So that should be a script, right? yes Then I can load it in file/source R code. source( yourScript.R ) check working path: getwd() if you don't know what this is: ?getwd ?source First, can anyone confirm that I took the correct approach for the problem? yes I understand R is quite different from program language like C/Pascal which I am familiar with and seems people write it with quite different style. it's a functional language and inherits from LISP (Scheme). You need to read the manual. Second, can anyone show me some idea about how to write the comment.
