Expression De-Parsing

Description

Turn unevaluated expressions into character strings.

Arguments

expr	any R expression.
collapse	a string, passed to paste()
width.cutoff	integer in [20, 500] determining the cutoff (in bytes) at which line-breaking is tried.
...	further arguments passed to deparse().

Details

This is a simple utility function for R < 4.0.0 to ensure a string result (character vector of length one), typically used in name construction, as util_deparse1(substitute(.)).

This avoids a dependency on backports and on R >= 4.0.0.

Value

the deparsed expression
