Dear R-devel, There is a new feature in R-devel, which explicitly refers to LISP @ operator for splicing. > The backquote function bquote() has a new argument splice to enable splicing a computed list of values into an expression, like ,@ in LISP's backquote. Although the most upvoted SO question asking for exactly LISP's @ functionality in R doesn't seems to be addressed by this

...and side, you're artificially bypassing the left-associativity of these operators. To achieve what you're looking for in a general way, you'll need a more precise definition of the problem, and a solution that probably involves rotating the AST accordingly (see https://github.com/r-lib/rlang/blob/master/src/internal/expr-interp-rotate.c). Maybe it could be possible to formulate a definition where splicing in special calls like binary operators produces the same AST as the user would type by hand. It seems this would make splicing easier to use for end users, but make the metaprogrammin...

The most likely explanation is you have a new version of dplyr/tibble and an old version of rlang. Try re-installing rlang.

...t; > names(list(...)) > > do what you want? No, that does what he asked for, not what he wants :-). Spencer, you want to deparse all of the expressions in ..., not their names. I think base R doesn't have a way to do this (but I may be wrong). You can do it using some the rlang package. For example, this seems to work: deparseDots <- function(...) { unname(sapply(rlang::exprs(...), deparse)) } Duncan Murdoch

If you can afford a dependency on rlang, `rlang::zap_srcref()` deals with this. It's recursive over expression vectors, calls (including calls to `function` and their hidden srcref arg), and function objects. It's implemented in C for efficiency as we found it to be a bottleneck in some applications (IIRC caching). I'd be hap...
