hoard
- manage cached files
Exposes a single R6
object so that when the package is imported in another package for managing cached files, you don’t need to pollute the NAMESPACE with a bunch of functions. (you can always just hoardr::fxn
, but with a single object there are other benefits as well [maintaining state, e.g.]).
initialize client
(x <- hoardr::hoard())

set cache path
x$cache_path_set("foobar", type = 'tempdir')
#> [1] "/var/folders/fc/n7g_vrvn0sx_st0p8lxb3ts40000gn/T//RtmpWAAkp3/R/foobar"
make the directory if doesn’t exist
x$mkdir()
put a file in the cache
list the files
x$list()
