wrapr (version 1.5.0)

qc: Quoting version of c() array concatinator.

Description

The qc() function is intended to help quote user inputs. It is a convenience function allowing the user to elide excess quotation marks. It quotes its arguments instead of evaluating them, except in the case of a nested call to qc() itself. Please see the examples for typical uses both for named and un-named character vectors.

Usage

qc(sin(x))  # returns the string "sin(x)"

qc(a, qc(b, c)) # returns c("a", "b", "c")

qc(x=a, qc(y=b, z=c)) # returns c(x="a", y="b", z="c")

qc('x'='a', wrapr::qc('y'='b', 'z'='c')) # returns c(x="a", y="b", z="c")
