Create pairlists with splicing support
This pairlist constructor uses dynamic dots. Use it to manually create argument lists for calls or parameter lists for functions.
pairlist2(...)
... |
<dynamic> Arguments stored in the pairlist. Empty arguments are preserved. |
# Unlike `exprs()`, `pairlist2()` evaluates its arguments. new_function(pairlist2(x = 1, y = 3 * 6), quote(x * y)) new_function(exprs(x = 1, y = 3 * 6), quote(x * y)) # It preserves missing arguments, which is useful for creating # parameters without defaults: new_function(pairlist2(x = , y = 3 * 6), quote(x * y))
