- x
A data frame or tibble to write to disk.
- file
File or connection to write to.
- delim
Delimiter used to separate values. Defaults to \t
to write
tab separated value (TSV) files.
- eol
The end of line character to use. Most commonly either "\n"
for
Unix style newlines, or "\r\n"
for Windows style newlines.
- na
String used for missing values. Defaults to 'NA'.
- col_names
If FALSE
, column names will not be included at the top of the file. If TRUE
,
column names will be included. If not specified, col_names
will take the opposite value given to append
.
- append
If FALSE
, will overwrite existing file. If TRUE
,
will append to existing file. In both cases, if the file does not exist a new
file is created.
- quote
How to handle fields which contain characters that need to be
quoted.
needed
- Values are only quoted if needed: if they contain a delimiter,
quote, or newline.
all
- Quote all fields.
none
- Never quote fields.
- escape
The type of escape to use when quotes are in the data.
double
- quotes are escaped by doubling them.
backslash
- quotes are escaped by a preceding backslash.
none
- quotes are not escaped.
- bom
If TRUE
add a UTF-8 BOM at the beginning of the file. This is
recommended when saving data for consumption by excel, as it will force
excel to read the data with the correct encoding (UTF-8)
- num_threads
Number of threads to use when reading and materializing
vectors. If your data contains newlines within fields the parser will
automatically be forced to use a single thread only.
- progress
Display a progress bar? By default it will only display
in an interactive session and not while knitting a document. The display
is updated every 50,000 values and will only display if estimated reading
time is 5 seconds or more. The automatic progress bar can be disabled by
setting option readr.show_progress
to FALSE
.
- path
is no longer supported, use
file
instead.
