In summary, strings are read by default as factors (i.e. distinct groups). This has two consequences: Your data is stored more efficiently, because each unique string gets a number and whenever it's used in your data frame you can store its numerical value (which is much smaller in size) Factors are set when the data-frame is created (or file loaded). Only stings present at that time will become factors. If you try and assign any other value to that column, and it's not in the list of factor strings, you'll get an error. The good thing is this prevents entering wrong data into a set data frame, the downside is it's very annoying when you want to alter data frames.(There are ways to add or change factors, but it's often cumbersome) In short, use stringAsFactors = F if you're planning to change the type of strings you're going to use in your data frame. If the data will not be changed.
The argument 'stringsAsFactors' is an argument to the 'data. frame ()' function in R. It is a logical that indicates whether strings in a data frame should be treated as factor variables or as just plain strings.

This is amazing
is stringasfactors is necessary
That is amazing
Why we write stringAsFactors=False? Please explain it
The argument 'stringsAsFactors' is an argument to the 'data. frame ()' function in R. It is a logical that indicates whether strings in a data frame should be treated as factor variables or as just plain strings.
