Hi,
I have the following problem: I want to redefine the for loop (or define a similar statement) to change its behavior under some circumstances. So, I would like sthg. like "For" = function ( var, vec, statement ) { if ( ... ) { /* my implementation of for */ } else { /* call R's for loop */ } } I tried to manipulate the elements of the list one gets by e = quote( for ( i in (1:10) ) print("*") ) That means, storing the variable in e[[2]] (my trials didn't work), and the statement in e[[4]], but I failed. How can one do this in R? It would be best, if I could redefine "for" directly, so that one can use the same syntax, i.e., with the statement after the function call. Can somebody help me? Thanks! { -- Jetzt dabei sein: http://www.shortview.de/[EMAIL PROTECTED] ______________________________________________ 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.
