connector (version 0.1.0)

write_file: Write files based on the extension

Description

write_file() is the backbone of all write_cnt() methods, where files are written to a connector. The function is a wrapper around write_ext() where the appropriate function to write the file is chosen depending on the file extension.

write_ext() has methods defined for the following file extensions:

• txt: readr::write_lines()

• csv: readr::write_csv()

• parquet: arrow::write_parquet()

• rds: readr::write_rds()

• sas7bdat: haven::write_sas()

• yml/yaml: yaml::write_yaml()

• json: jsonlite::write_json()

• excel: writexl::write_xlsx()

Usage

write_file(x, file, overwrite = FALSE, ...)
write_ext(file, x, ...)
# S3 method for txt
write_ext(file, x, ...)
# S3 method for csv
write_ext(file, x, delim = ",", ...)
# S3 method for parquet
write_ext(file, x, ...)
# S3 method for rds
write_ext(file, x, ...)
# S3 method for xpt
write_ext(file, x, ...)
# S3 method for yml
write_ext(file, x, ...)
# S3 method for json
write_ext(file, x, ...)
# S3 method for xlsx
write_ext(file, x, ...)

Value

write_file(): invisible() file.

write_ext(): The return of the functions behind the individual methods.

Other parameters passed on the functions behind the methods for each file extension.
