Description

CSV Writing Options

Usage

csv_write_options(
  include_header = TRUE,
  batch_size = 1024L,
  null_string = "",
  delimiter = ",",
  eol = "\n",
  quoting_style = c("Needed", "AllValid", "None")
)

Arguments

include_header	Whether to write an initial header line with column names
batch_size	Maximum number of rows processed at a time.
null_string	The string to be written for null values. Must not contain quotation marks.
delimiter	Field delimiter
eol	The end of line character to use for ending rows
quoting_style	How to handle quotes. "Needed" (Only enclose values in quotes which need them, because their CSV rendering can contain quotes itself (e.g. strings or binary values)), "AllValid" (Enclose all valid values in quotes), or "None" (Do not enclose any values in quotes).

Examples

tf <- tempfile()
on.exit(unlink(tf))
write_csv_arrow(airquality, tf, write_options = csv_write_options(null_string = "-99"))
