The solution code is written in R script.

#string variable character_str< - "Hello World" #logical variable logic b #Missing value myVec <-c (1, 2, 3, NA) #Use class to check data type class (character_str) class (logic) class (myVec)

Explanation:

A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)

A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).

In R, missing value is an unknown value which is represented by NA symbol (Line 8).

We can use in-built method class to check for the variable type in R (Line 11-13). For example, the output of class (character_str) is "character"
