csv_write_options function

CSV Writing Options

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"))
