Dear all, I have a problem when passing parms from one function to another when
the argument list is just '...'. Consider this example:
foo<-function(){
xx <- 111222
bar(x=xx)
}
bar <- function(...){
cl <- match.call(expand.dots=TRUE)
print(cl)
x <- eval(cl$x)
print(x)
}
foo()
> bar(x = xx)
> Error in eval(expr, envir, enclos) : Object "xx" not found
My expectation was, that xx would be evaluated to 111222 in foo before being
passed on to bar, but obviously it is not so. Should I do something explicitely
in foo() to 'evaluate' xx or need I do something special in bar()??
Thanks in advance, Søren
