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 class 'txt'
write_ext(file, x, ...)
# S3 method for class 'csv'
write_ext(file, x, delim = ",", ...)
# S3 method for class 'parquet'
write_ext(file, x, ...)
# S3 method for class 'rds'
write_ext(file, x, ...)
# S3 method for class 'xpt'
write_ext(file, x, ...)
# S3 method for class 'yml'
write_ext(file, x, ...)
# S3 method for class 'json'
write_ext(file, x, ...)
# S3 method for class 'xlsx'
write_ext(file, x, ...)Arguments
- x
Object to write
- file
character()Path to write the file.- overwrite
logical Overwrite existing content if it exists.
- ...
Other parameters passed on the functions behind the methods for each file extension.
- delim
character()Delimiter to use. Default is",".
Value
write_file(): invisible() file.
write_ext(): The return of the functions behind the individual methods.
Details
Note that write_file() will not overwrite existing files unless overwrite = TRUE,
while all methods for write_ext() will overwrite existing files by default.
Examples
# Write CSV file
temp_csv <- tempfile("iris", fileext = ".csv")
write_file(iris, temp_csv)
