tidyeval: Tidy eval helpers

In olascodgreat/samife: A Grammar of Data Manipulation

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.
