renv::init ignores interactive snapshot type

[cstepper]

Hi,

we're trying to use the renv::init function using the explicit snapshot type (only capturing the dependencies as declared in the DESCRIPTION).
It looks like the snapshot type is ignored when submitted interactively as opposed to setting it in advance.

---

Our workflow was as follows: (in a new package without any dependencies):

1. setup a package without dependencies (using usethis::create_package())
2. add a function using tibble package ( use_r("tibble.R")) without adding tibble as package dependency to DESCRIPTION
3. run renv::init() interactively

renv::init()
#> This project contains a DESCRIPTION file.
#> Which files should renv use for dependency discovery in this project? 
#>   
#> 1: Use only the DESCRIPTION file. (explicit mode)
#> 2: Use all files in this project. (implicit mode)
#> 
#> Selection: 1
#> 
#> - Using 'explicit' snapshot type. Please see `?renv::snapshot` for more details.
#> 
#> - Linking packages into the project library ... Done!
#>   The following package(s) will be updated in the lockfile:
#>   
#>   # CRAN -----------------------------------------------------------------------
#> - cli         [* -> 3.6.1]
#> - glue        [* -> 1.6.2]

It looks like all package dependencies from tibble are written to the renv.lock (as we assume is "implicit" mode, not "explicit"). Also, in renv/settings.json snapshot type "implicit" is defined, not "explicit" as chosen interactively.

In contrast, when manually setting the type before renv::init() it seems to work as expected:

renv::settings$snapshot.type("explicit")
renv::init()
#> The following package(s) will be updated in the lockfile:
#>   
#>   # CRAN -----------------------------------------------------------------------
#> - renv   [* -> 1.0.0]
#> 
#> The version of R recorded in the lockfile will be updated:
#>   - R      [* -> 4.3.1]
#> 
#> - Lockfile written to '~/cstepper/justfortesting/renvtestr/renv.lock'.
#> 
#> Restarting R session...
#> 
#> - Project '~/cstepper/justfortesting/renvtestr' loaded. [renv 1.0.0]
#> 

Any ideas?
Thanks

Thanks for the bug report! This should now be fixed in the development version of renv.
