dear R experts---I am trying to replicate a perl feature. I want to be able to embed R commands inside a character string, and have the string be printed with the command executed. my perl equivalent is my $a=10; my $teststring = "the expression, $a+1, is ::$a+1::, but add one more for ::$a+2::\n"; $teststring =~ s/::(.*?)::/$1/gee; print $teststring; of course, R does not use '$' for variable names. my ultimate goal is to write something like cat("d is a ::class(d):: with names ::names(d):...

Dear All, it seems to me that levels() deletes other attributes. See the following example: ## example with levels f1 <- factor(c('level c','level b','level a','level c'), ordered=TRUE) attr(f1, 'testattribute') <- 'teststring' attributes(f1) levels(f1) <- c('L-A', 'L-B', 'L-C') attributes(f1) If I run it, after assigning new levels, the class is only "factor" instead of "ordered" "factor" and the $testattribute "teststring" is gone. The same happen...

Consider this Java class: class myClass { final public static String[] testString () { return new String[]{"my", "name", "is"} ; } final public static int[] testInt () { return new int[]{5, 10, 15}; } final public static char[] testChar () { return new char[]{'x', 'y', 'z'...
