Vectors

Vectors:

--------------------------------------------------------------------------------------------------------------------------

there are six types in the Vectors:

--------------------------------------------------------------------------------------------------------------------------

Logical -- when  a value is true or false, then it shoes the class of the value:

for example:

> vectorone <- TRUE

assigning TRUE to the vectorone variable 

> print(vectorone)

printing thevariable

Output

[1] TRUE

> print(class(vectorone))

printing the class of the vectorone

 

Output:

[1] "logical"

--------------------------------------------------------------------------------------------------------------------------

> vectorone <- 26.5

assigning the numerical value for variable vectorone

> print(vectorone)

printing the vectorone

Output

[1] 26.5

> print(class(vectorone)) 

printing the class of the vector

Output:

[1] "numeric"

> vectorone <- 23

assigning the value for the vectorone

> print(vectorone)

printing the value

Output:

[1] 23

> print(class(vectorone))

printing the class of the variable

 Output

[1] "numeric"

------------------------------------------------------------------------------------------------------------------------- 

> vectortwo<-"your name"

Assigning the value for vectortwo

> print(vectortwo)

printing the value of the variable

Output

[1] "your name"

printing the class of the variable

Output

> print(class(vectortwo))

[1] "character"

--------------------------------------------------------------------------------------------------------------------------

 vector3 <- 1L

Assigning the value for the vector3

printing the vector3

> print(vector3)

Output:

[1] 1

printing the class of the vector3 

> print(class(vector3))

Output:

[1] "integer"

--------------------------------------------------------------------------------------------------------------------------

> vector4 <- 1+2i

assigning the complex value for the vector4

> print(vector4)

printing the vector4

Output

[1] 1+2i

printing the class of the vector3

> print(class(vector4))

Output

[1] "complex"

--------------------------------------------------------------------------------------------------------------------------

To create vector more than one value , we use c() it is a combiner function then the syntax ill be in the following format, 

> vector5 <- c("firstname",2L,23.6,2+3i,TRUE)

assigning multiple values to the vector5

> print(vector5)

printing vector5

Output

[1] "firstname" "2"         "23.6"      "2+3i"      "TRUE" 

Printing the class of the vector5:

Output    

> print(class(vector5))

[1] "character"
