Documentation examples seem wrong

[barryrowlingson]

The readme.md documentation section "PROCESSING" has:

name <- opt_get( "--name" )
date <- opt_get( "--date", default=Sys.Date )

which doesn't seem to work because the -- signs are in the quoted string. I get NA values when I specify an option:

$ R --args --name=foo --date=now
> library(optigrab)
optigrab-0.9.2.1 (2019-01-05) - Copyright © 2019 Decision Patterns
> opt_get("name")
[1] "foo"
> opt_get("--name")
[1] NA

I think the documentation should be:

name <- opt_get( "name" )
date <- opt_get( "date", default=Sys.Date )
