This is not really a question on R, but a question for a book on R that I am writing for psychology graduate students. Students in psychology often have little exposure to linear algebra when they show up in grad school (and often when they leave!). I would like to include a page in my R text that discusses standard notation for matrices and vectors. I realize that there is no universal standard, but I recall seeing a reference to a so-called "international standard" with the customary: lowercase for scalars, bold lowercase for vectors, etc. Does anyone know where such a standard is published? Many thanks for any hints, Niels ******************************************************* Niels Waller, Ph.D. Director of Quantitative Methods and Evaluation Department of Psychology and Human Development Vanderbilt University Phone: (615) 322-8380 email: niels.waller at vanderbilt.edu QME Home page: http://www.vanderbilt.edu/quantmetheval/ ******************************************************* -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
