Local board (legacy API)

legacy_local() powers board_register_local(), which allows you to access local pins created in earlier versions of the pins package. For new pins, we recommend that you transition to board_local() which supports the new pins API.

legacy_temp() creates a legacy board in a temporary location, for use in tests and examples.

Usage

legacy_local(path = NULL, name = "local", versions = FALSE)

board_register_local(name = "local", cache = NULL, ...)

legacy_temp(name = "temp", ...)

Arguments

path

Path where pins will be stored. If not supplied, defaults to a system cache directory, which may be deleted by the operating system if you run out of disk space.

name

An optional name used identify the board. This is no longer generally needed since you should be passing around an explicit board object.

versions

Should this board be registered with support for versions?

cache

Cache path. Every board requires a local cache to avoid downloading files multiple times. The default stores in a standard cache location for your operating system, but you can override if needed.

...

Additional parameters required to initialize a particular board.

Examples

# Old api
pin(data.frame(x = 1:3), "test")
pin_get("test")
#>   x
#> 1 1
#> 2 2
#> 3 3

# New api
board <- board_local()
board %>% pin_write(data.frame(x = 1:3), "test")
#> Guessing `type = 'rds'`
#> Creating new version '20241213T233056Z-66fa6'
#> Writing to pin 'test'
board %>% pin_read("test")
#>   x
#> 1 1
#> 2 2
#> 3 3
