As part of series Learn Data analytics using R lets understand basic syntax in this post.
Numeric Data Type
Lets say you want to create two variable A and B. In R program you shall assign a value to the variable using <- . Now, if you want to assign 25 to A and 29 to B. You can use the following code.
A<-25 B<-29
You can add both variable by simply using + operator
> A+B [1] 54
Character Data Type
The above example is for assigning numeric value. If you need to assign a character/word to the variable you can do so by adding a quotations "".
A<-"Arsenal"
Now, Variable A is assigned with a text value of “Arsenal”. Character and Numeric are data types.
Logical Data Type
R is also capable of storing Logical data type like TRUE/FALSE
C<-is.numeric(B) > C [1] TRUE
Finding a data type
You can use class() to find the data type of a variable
class(A) [1] "character" > class(B) [1] "numeric" > class(C) [1] "logical"
