Miscellaneous Operators

These operators are used to for specific purpose and not general mathematical or logical computation.

Operator Description Example

Colon operator. It creates the series of numbers in sequence for a vector.

Operator	Description	Example
:	Colon operator. It creates the series of numbers in sequence for a vector.	`a` it produces the following result − `[1] 2 3 4 5 6 7 8`
%in%	This operator is used to identify if an element belongs to a vector.	`a1` it produces the following result − `[1] TRUE [1] FALSE`
%*%	This operator is used to multiply a matrix with its transpose.	`R = matrix( c(2,6,5,1,10,4), nrow = 2,ncol = 3,byrow = TRUE) b = R %*% t(R) print(b)` it produces the following result − `[,1] [,2] [1,] 65 82 [2,] 82 117`

it produces the following result −

[1] 2 3 4 5 6 7 8

%in%

This operator is used to identify if an element belongs to a vector.

a1

it produces the following result −

[1] TRUE
[1] FALSE

%*%

This operator is used to multiply a matrix with its transpose.

R = matrix( c(2,6,5,1,10,4), nrow = 2,ncol = 3,byrow = TRUE)
b = R %*% t(R)
print(b)

it produces the following result −

[,1] [,2]
[1,]   65   82
[2,]   82  117
