R Documentation

Read a csv file into a tibble, and type columns using a separate json file.

Description

Read a csv file into a tibble, and type columns using a separate json file.

Usage

readtype_csv(
  file,
  suffix = "",
  delim,
  quote = "\"",
  escape_backslash = FALSE,
  escape_double = TRUE,
  locale = default_locale(),
  na = c("", "NA"),
  quoted_na = TRUE,
  comment = "",
  trim_ws = FALSE
)

Arguments

`file`	Delimited file location.
`suffix`	The suffix used in the name of the json file, which is 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`	Single character used to separate fields within a record.
`quote`	Single character used to quote strings.
`escape_backslash`	Does the file use backslashes to escape special characters? This is more general than `escape_double` as backslashes can be used to escape the delimiter character, the quote character, or to add special characters like `⁠\\n⁠`.
`escape_double`	Does the file escape quotes by doubling them? i.e. If this option is `TRUE`, the value `⁠""""⁠` represents a single quote, `⁠\"⁠`.
`locale`	The locale controls defaults that vary from place to place. The default locale is US-centric (like R), but you can use `locale()` to create your own locale that controls things like the default time zone, encoding, decimal mark, big mark, and day/month names.
`na`	Character vector of strings to interpret as missing values. Set this option to `character()` to indicate no missing values.
`quoted_na`	Should missing values inside quotes be treated as missing values (the default) or strings. This parameter is soft deprecated as of readr 2.0.0.
`comment`	A string used to identify comments. Any text after the comment characters will be silently ignored.
`trim_ws`	Should leading and trailing whitespace (ASCII spaces and tabs) be trimmed from each field before parsing it?

Details

Based on the readr::read_csv function. Requires csv files to be saved using writetype_csv, which will also create the json file containing the typing info. Datetime and time classes are not supported.
