= How do I make bibliographic citations of a SPSS or R procedure? = The below is taken directly from the SPSS website [[http://www.spss.com/corpinfo/faqs.htm#book|here.]] For most of our products, you can get the complete product name, version or release number and date of creation from the "About . . ." dialog box that appears under the "Help" menu. For example, if you have SPSS for Windows, you might see this: SPSS for Windows Release 11.0.1 (15 Nov 2001) You can then write a bibliographic citation as follows: SPSS for Windows, Rel. 11.0.1. 2001. Chicago: SPSS Inc. If you are referencing material from the SPSS Web site, please refer to the terms and conditions [[http://www.spss.com/terms.htm|here.]] typing {{{ citation() }}} at an R prompt will give the citation for referencing R procedures: e.g. in R 2.14.2 we get R Development Core Team (2012).
