bquote | R Documentation |
An analogue of the LISP backquote macro. bquote
quotes its
argument except that terms wrapped in .()
are evaluated in the
specified where
environment. If splice = TRUE
then
terms wrapped in ..()
are evaluated and spliced into a call.
bquote(expr, where = parent.frame(), splice = FALSE)
expr |
A language object. |
