What is a Vector?
If you are familiar with any other programming language, you may superficially guess what vector is. In simple wording, it's like an array in which you can store multiple values. But why should we start learning data types with arrays straightaway?
The answer is simple - even simple numbers (real, integer, complex), a text string is also considered as a vector, having the length of 1. So let's stop with the single-element vectors. What types are available in R? These are:
logical- storing logical valuesTRUE/TandFALSE/F.numeric/double- consists of real numbers.integer- consists of integer numbers.complex- consists of complex numbers.character- consists of characters (text).
To check the type of a specific variable, you need to use the typeof() function, passing the necessary variable as a parameter. For example,
test = TRUE typeof(test)
The output of the script above is:
Practice using this function by yourself!
