Passing a string to tar_read?

[mike-lawrence]

I'm probably misusing things somewhere, but I'm playing with the excellent stantargets with a static branching pattern to explore multiple models under different data size conditions, and I can get the list of resulting targets by filtering the metadata, but I'm having trouble then programatically retrieving the corresponding objects using tar_read presumably thanks to tidy-eval stuff I'm still not great with. Here's what I have, with things I've tried as commented-out entries at the end:

(
  tar_meta()
  %>% filter(
    type=='pattern'
    , !str_contains(name,'_data')
  ) 
  %>% pull(name)
  #works up to here

  # %>% map_dfr( .f = tar_read ) #doesn't work

  # %>% map_dfr( .f = tar_read(!!.) ) #doesn't work

  # %>% map_dfr( .f = function(x) { tar_read(!!x) } ) #doesn't work  
)

tar_read_raw() can accept a string. Alternatively, tar_load() accepts tidyselect syntax. To create a list using tar_load():

envir <- new.env()
tar_load(ends_with("_data"), envir = envir)
as.list(envir)
