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.	a <- 2:8 print(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 <- 8 a2 <- 12 b <- 1:10 print(a1 %in% b) print(a2 %in% b) 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
