Usage

Arguments

x	Specify the character variable whose letters to be changed into uppercase or lowercase.
charlower	Specify whether you want to get the uppercase letters or lowercase letters. It defaults to change all the letters into lowercase.

Details

UorL is an easy function to convert the letters for a character variable into uppercase or lowercase.

Value

UorL returns the results of conversion directly.

Note

None.
