Question - Using as.period within a package #664

Description

@rsangole

Hello,

Situation

I don't wish to write require(lubridate) in my package. However, not doing so results in an error.

Error & Reproducible Example

  • Doesn't work:

In a brand new R session.

lubridate::as.period(x = 10, unit = 'day')
#> Error in get(as.character(FUN), mode = "function", envir = envir): object 'days' of mode 'function' was not found
  • Works:

In a brand new R session.

library('lubridate')
#> 
#> Attaching package: 'lubridate'
#> The following object is masked from 'package:base':
#> 
#>     date
lubridate::as.period(x = 10, unit = 'day')
#> [1] "10d 0H 0M 0S"

Why is this behavior true?

Background

I'm writing a package which uses the lubridate::as.period function and would like to make a call like:

historic_timeperiod <- lubridate::as.period(30, units='days')

(In the package, lubridate is set as Imports:)
