R Documentation

Write a data frame to a delimited file, and save typing information in a separate json file

Description

Write a data frame to a delimited file, and save typing information in a separate json file

Usage

writetype_delim(
  x,
  path,
  suffix = "",
  delim = " ",
  na = "NA",
  quote_escape = "double",
  eol = "\n"
)

Arguments

`x`	A data frame or tibble to write to disk.
`path`	File or connection to write to. (path is now deprecated in readr v1.4 for OpenSAFELY currently has older version, so use path for now)
`suffix`	The suffix used in the name of the json file, to be appended to the delimited file name. Defaults to `""` (no suffix), so that the file name is the same as the delimited file name (excluding filetype extensions).
`delim`	Delimiter used to separate values.
`na`	String used for missing values. Defaults to `"NA"`. Missing values will never be quoted; strings with the same value as `na` will always be quoted.
`quote_escape`	The type of escaping to use for quoted values, one of "`double`", "`backslash`" or "`none`". You can also use `FALSE`, which is equivalent to "`none`". The default is "`double`", which is expected format for Excel.
`eol`	The end of line character to use. Most commonly either "`⁠\n⁠`" for Unix style newlines, or "`⁠\r\n⁠`" for Windows style newlines.

Details

Based on the readr::write_delim function. Additionally, this function saves a json file containing typing info for the data frame, which can be used to re-type the data when re-imported into R. Some further readr::write_delim options are deliberately unavailable as they won't make sense for files intended for re-importing. Datetime and time classes are not supported.
