tidyeval {dplyr} | R Documentation

## Tidy eval helpers

### Description

- `sym()` creates a symbol from a string and `syms()` creates a list of symbols from a character vector.

- `expr()` and `quo()` quote one expression. `quo()` wraps the quoted expression in a quosure.

  The plural variants `rlang::exprs()` and `quos()` return a list of quoted expressions or quosures.

- `enexpr()` and `enquo()` capture the expression supplied as argument by the user of the current function (`enquo()` wraps this expression in a quosure).

  `enexprs()` and `enquos()` capture multiple expressions supplied as arguments, including `...`.

`exprs()` is not exported by dplyr to avoid conflicts with `Biobase::exprs()`. Use `rlang::exprs()` even if you have attached dplyr.
