Create input and output paths — init

`init_path()` creates paths that will be used to find input data and save outputs.

init_path(input, output = tempdir(), default = TRUE, classification = NULL)

Arguments

input: named character vector indicating where to find inputs. This vector defines the path where to look for files in priority. If nothing is specified, paths will be set to `system.file("extdata", "default", package = "floodam.agri")`.
output: character, path for output. Default to `tempdir()`.
default: logical, should "default" path be created. If TRUE, "default" path will be set to `system.file("extdata", "default", package = "floodam.agri")`. Default to TRUE.
classification: character giving the path to the folder which contains classification references. If NULL, no path is created. Default to NULL.

Value

list of character, paths created.

Details

`input` parameter: The order of each element in `input` is important as it will define the order in which inputs will be searched in `path[["extent"]]`.

Examples


path = init_path()

# Unnamed input vector
input = c(
    system.file(
        "extdata",
        "example",
        "local",
        "winery",
        package = "floodam.agri"
    ),
    system.file(
        "extdata",
        "regional",
        "Occitanie",
        "2016",
        package = "floodam.agri"
    ),
    system.file("extdata", "national", package = "floodam.agri")
)
path = init_path(input)
print(path[["extent"]])
#> [1] "user_01" "user_02" "default"

path = init_path(input, default = FALSE)
print(path[["extent"]])
#> [1] "user_01" "user_02"

names(input) = c("local", "regional", "national")
path = init_path(input)
print(path[["extent"]])
#> [1] "local"    "regional" "default"
