This is equivalent to vroom_write(), but instead of writing to
disk, it returns a string. It is primarily useful for examples and for
testing.
vroom_format(
x,
delim = "\t",
eol = "\n",
na = "NA",
col_names = TRUE,
escape = c("double", "backslash", "none"),
quote = c("needed", "all", "none"),
bom = FALSE,
num_threads = vroom_threads()
)A data frame or tibble to write to disk.
Delimiter used to separate values. Defaults to \t to write
tab separated value (TSV) files.
The end of line character to use. Most commonly either "\n" for
Unix style newlines, or "\r\n" for Windows style newlines.
String used for missing values. Defaults to 'NA'.
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.
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.
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.
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)
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.
