  • A variable name in R programming language can contain numeric and alphabets along with special characters like dot (.) and underline (-). 
  • Variable names in R language can begin with an alphabet or the dot symbol. However, if the variable name begins with a dot symbol it should not be a followed by a numeric digit.
