Can you describe a situation where you would need to change the data type of a variable in R?

  • When a data is stored in an incorrect format
  • When a date is stored as a character
  • When a factor is stored as a character
  • When a numeric value is stored as a character
Sometimes, data read from text files or over the network may be in character format, but we may need it to be in a numeric format for mathematical operations. In this case, we would need to convert the character data to numeric.
