utils_clean_names: Clean Character Vector of Names

Description

Clean and format character vectors for use as column names or variable names.

Usage

utils_clean_names(
  x = NULL,
  lowercase = FALSE,
  separator = "_",
  capitalize_first = FALSE,
  capitalize_all = FALSE,
  length = NULL,
  suffix = NULL,
  prefix = NULL
)

Value

character vector

Arguments

x

(required, character vector) Names to be cleaned. Default: NULL

lowercase

(optional, logical) If TRUE, all names are coerced to lowercase. Default: FALSE

separator

(optional, character string) Separator when replacing spaces and dots and appending suffix and prefix to the main word. Default: "_".

capitalize_first

(optional, logical) Indicates whether to capitalize the first letter of each name Default: FALSE.

capitalize_all

(optional, logical) Indicates whether to capitalize all letters of each name Default: FALSE.

length

(optional, integer) Minimum length of abbreviated names. Names are abbreviated via abbreviate(). Default: NULL.

suffix

(optional, character string) String to append to the cleaned names. Default: NULL.

prefix

(optional, character string) String to prepend to the cleaned names. Default: NULL.

Details

The cleanup operations are applied in the following order:

• Remove leading and trailing whitespaces.

• Generates syntactically valid names with base::make.names().

• Replaces dots and spaces with the separator.

• Coerces names to lowercase.

• If argument length is provided, base::abbreviate() is used to abbreviate the new column names.

• If suffix is provided, it is added at the end of the column name using the separator.

• If prefix is provided, it is added at the beginning of the column name using the separator.

• If capitalize_first = TRUE, the first letter is capitalized.

• If capitalize_all = TRUE, all letters are capitalized.
