clean_names

0th

Percentile

Cleans names of a data.frame.

Resulting names are unique and consist only of the _ character, numbers, and letters. Capitalization preferences can be specified using the case parameter.

Accented characters are transliterated to ASCII. For example, an "o" with a German umlaut over it becomes "o", and the Spanish character "enye" becomes "n".

Usage
clean_names(dat, case = c("snake", "lower_camel", "upper_camel",
  "screaming_snake", "lower_upper", "upper_lower", "all_caps",
  "small_camel", "big_camel", "old_janitor", "parsed", "mixed"))
Arguments
dat

the input data.frame.

case

The desired target case (default is "snake"), indicated by these possible values:

  • "snake" produces snake_case

  • "lower_camel" or "small_camel" produces lowerCamel

  • "upper_camel" or "big_camel" produces UpperCamel

  • "screaming_snake" or "all_caps" produces ALL_CAPS

  • "lower_upper" produces lowerUPPER

  • "upper_lower" produces UPPERlower

  • old_janitor: legacy compatibility option to preserve behavior of clean_names prior to addition of the "case" argument(janitor versions <= 0.3.1 ). Provided as a quick fix for old scripts broken by the changes to clean_names in janitor v1.0.

  • "parsed", "mixed", "none", "internal_parsing": less-common cases offered by snakecase::to_any_case. See to_any_case for details.

Value

Returns the data.frame with clean names.
