Vectors data structures in R consist of order collection of numbers, characters, or strings. There are two major types of vectors:
To create a vector named x, with values namely 10, 20, 30, 3.5 and 3.8, use c() function in R command:
x <- c(10, 20, 30, 3.5, 3.8)
Note: The
c()function will return a vector.
There are various methods or operators in R to perform assignment operations. Let’s discuss some techniques to perform this operation on vectors.
<- operatorThis assignment operator(<-) consists of two characters:
< (less than)- (minus)These two characters occur side by side, while the tip points to a variable will receive an assignment value. The assignment of <- operator is also possible in reverse direction ->.
Let’s look at the code below:
# USING <- OPERATORcat("Arrow assignment: ")x <- c(10, NA, 30, 'shot', 3.8)cat(x, end='\n')# Assignment operator in reverse directionc(10.4, 5.6, 3.1, 6.4, 'AB') -> ycat("Revered arrow assignment: ", y, end='\n')
c() function and assign it to the x variable using <- operator.x on console.c() function and assign it to y variable using -> reversed operator.y to the console.= operatorEqual to (=) operator is also used for value assignment. So, we can perform the above operation like:
x = c(9, 8, 23, 4.5, 9.8)
Let’s understand the equal = operator with the help of a code example:
# USING = OPERATORx = c(10, NA, 30, 'shot', 3.8)cat(x)
x using the c() function and equal to = operator.x to the console.assign()Assignment can also be made by using the assign() method. It’s an equivalent method of assignment as above.
In the example below, we use the assign() function in detail:
# USING assign() FUNCTIONassign("x", c(10, NA, 30, 'Edpresso', 3.8))cat(x)
assign() function for assignment second argument value to first one.x to the console.
