Create a write expression for a single file

Convenience wrapper that detects the file format from the path extension and returns an unevaluated R expression for writing the data. Useful for sibling packages that construct pipelines programmatically (e.g. DM blocks).

Usage

write_file_expr(data, path, ...)

Arguments

data

Character. Name of the data object to write.

path

Character. Output file path (extension determines format).

...

Additional parameters forwarded to the writer (e.g. sep, quote, na for CSV files).

Value

A language object (unevaluated call) that, when evaluated, writes the data frame to the file.

Examples

write_file_expr("mtcars", "/tmp/cars.csv")
#> readr::write_csv(x = mtcars, file = "/tmp/cars.csv", quote = "needed", 
#>     na = "NA")
write_file_expr("iris", "/tmp/flowers.xlsx")
#> writexl::write_xlsx(x = list(iris = iris), path = "/tmp/flowers.xlsx")
write_file_expr("df", "/tmp/data.parquet")
#> arrow::write_parquet(x = df, sink = "/tmp/data.parquet")
