opt_assign: Parse options and assign values

In optigrab: Command-Line Parsing for an R World

Description

Combines opt_get and assign for convenience.

Usage

opt_assign(x, pos = 1, inherits = FALSE, name = x, ...,
  assign.na = FALSE)

opt_assign_all(x, ..., assign.na = FALSE)

Arguments

x	character or list; variable names or alias. If no coercion is done, and the first element of a character vector of length greater than one will be used, with a warning.
pos	where to do the assignment. By default, assigns into the current environment. See 'Details' for other possibilities.
inherits	logical; should the enclosing frames of the environment be inspected? This is argument is supplied to base::assign().
name	character; name(s) of option as passed to opt_get. (Default: 'x“)
...	arguments passed to opt_get
assign.na	logical; whether NA can be assigned. (Default: FALSE) opt_assign combines opt_get and assign in one call. The name argument is passed as opt_get(name=...); it defaults to x so it is generally not needed. opt_assign_all does multiple assignments but does not allow for a names arguments. Values are names by x.
