Being a newbie in respect to the use of R (but more experienced in respect to SPSS and Statistica), I am somewhat surprised at one thing. When using summary() to output the results from lm() you get what I would expect, with one exception, I am missing the standardized regression weights (beta's). Of course, it is possible to standardize all variables involved to get this information, but that is a rather brute approach. Is there a simpler approach I can show my students?
