Hi. In a case like this, I can get strip headings that have the name
"c" and the value for c.
d <- data.frame(a=1:5,b=6:10,c=11:15)
> xyplot(a ~ b | paste("c", c), data=d)
>
For more complicated examples, instead of using paste repeatedly I
would like to use a function. It seems like what I really want is a
macro, though. I'm not quite familiar enough with R's treatment of
function parameters to know how to do something like this (ficticious
example):
f <- function(x) { paste(identifier(x), value(x)) }
> rambo <- "brave"
> f(rambo)
"rambo brave"
I've checked ?function, ?args, ?eval, and some others, but I think
I'm barking up the wrong tree. Any pointers would be most
appreciated.
