    Numeric or Logical to Character type: Any character type values are always enclosed within double quotes(" ") Hence, the conversion of 20 of numeric type gets converted into "20" of character type Similarly, converting the FALSE of logical type into character type gives us "FALSE" Syntax: as character(value) Example: R
