Mark a file as external input to the script — external

Mark a file as external input to the script. This function simply returns the path and is used for static analysis to determine script dependencies. Unlike file_in(), external_in() is used for files that are provided by the user and are not produced by any other script in the pipeline. This helps distinguish between pipeline-internal dependencies and external data sources.

Usage

external_in(path)

Arguments

path: Character string specifying the path to the external input file

Value

The file path (unchanged)

Examples

# In a bakepipe script, mark a file as external input and use it directly
# user_data <- read.csv(external_in("input.csv"))
# config <- readRDS(external_in("config.rds"))

# The function simply returns the path unchanged
file_path <- external_in("input.csv")
print(file_path)  # "input.csv"
#> [1] "input.csv"
