I made the following example to see what are the difference between expression and quote. But I don't see any difference when they are used with eval()? Could somebody let me know what the difference is between expression and quote?
expr=expression(2*3) quo=quote(2*3) eval(expr) str(expr) class(expr) typeof(expr) mode(expr) attributes(expr) eval(quo) str(quo) class(quo) typeof(quo) mode(quo) attributes(quo) ______________________________________________ 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.
