In-string variable/symbol substitution: What formats/syntax is out there?
...'Biobase' package (with some efforts), e.g.
> bbsubst <- function(fmt, ...) {
args <- lapply(list(...), FUN=as.character)
in <- textConnection(fmt)
out <- textConnection("res", open="w")
on.exit({ close(in); close(out) })
copySubstitute(in, out, symbolValues=args)
res
}

string syntactic sugar in R? - long post

values of variables is done using 'paste' and can be
an error-prone and traumatic experience. For example,
when constructing a db query we have to write,
paste("SELECT " value " FROM table where
