ucfirst function

Uppercase the first letter in each word

ucfirst(x, lowercaseAll = FALSE, firstWordOnly = FALSE, ...)

Arguments

• x: character vector.
• lowercaseAll: logical indicating whether to force all letters to lowercase before applying uppercase to the first letter.
• firstWordOnly: logical indicating whether to apply the uppercase only to the first word in each string. Note that it still applies the logic to every entry in the input vector x.
• ...: additional arguments are ignored.

Returns

character vector where letters are converted to uppercase.

Details

This function is a simple mimic of the Perl function ucfirst which converts the first letter in each word to uppercase. When lowercaseAll=TRUE it also forces all other letters to lowercase, otherwise mixedCase words will retain capital letters in the middle of words.

Examples

ucfirst("TESTING_ALL_UPPERCASE_INPUT")
ucfirst("TESTING_ALL_UPPERCASE_INPUT", TRUE)
ucfirst("TESTING_ALL_UPPERCASE_INPUT", TRUE, TRUE)

ucfirst("testing mixedCase upperAndLower case input")
ucfirst("testing mixedCase upperAndLower case input", TRUE)
ucfirst("testing mixedCase upperAndLower case input", TRUE, TRUE)
