Greetings All. I want to do the following simple thing. I have defined a function med3x3() such that, given vectors X,Y, med3x3(X,Y) returns a 3x3 table where:
Row 1: X > median(X) Row 2: X = median(X) Row 3: X < median(X) Col 1: Y < median(Y) Col 2: Y = median(Y) Col 3: Y > median(Y) (with intersections of these conditions for the individual cells). I can easily define fixed rownames and colnames within the function so that the call meds3x3(G1,G2) returns a result that looks like: Y<Med Y=Med Y>Med X>Med 29 0 9 X=Med 4 0 1 X<Med 7 0 30 However, what I'd like to be able to do is pick up the names "G1" and "G2" from the function call so that the result looks like: G2<Med G2=Med G2>Med G1>Med 29 0 9 G1=Med 4 0 1 G1<Med 7 0 30 I could of course do this the tedious way by simply entering the name-strings "G1", "G2" as arguments as well as the variable names G1, G2, in a call like meds3x3(G1,G2,"G1","G2") But I'd like to simply be able to pick up, within the function, the names of the variables that were used as arguments in the function call. The only suggestion for doing so that I've found in a search of the R-help archives is in: http://finzi.psych.upenn.edu/Rhelp10/2010-May/240162.html which uses a somewhat rebarbative parsing of the call stack. Is there a simpler way? Or should I just use the 4-argument method? With thanks, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <ted.hard...@wlandres.net> Date: 25-Feb-2012 Time: 19:53:49 This message was sent by XFMail ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
