R Vector

Vector

• A Vector is a sequence of data elements of homogeneous type

• Elements in a vector are called as components

• Vectors can be created in many ways, few of them are:
  • by directly assigning the values to the objects

x <- 1:9
	y <- c(1,4,62,1,6,3,6,3,6)
	newText <- "This is R programming"
	moreText <- c("Hi", "Adding", "Multiple", "Words")
	letseelogical <- c(TRUE, FALSE, TRUE, FALSE, TRUE, TRUE)
	COMP1 <- c(6+3i, 2+4i)

Output:

Note : c() is a generic function which combines its arguments

• by using the following command :
  • > vector(mode= “” ,length = ‘n’ )
    
  • mode can have these options: numeric, integer, character, logical
  • > as.vector(x, mode = “”)
  
  a <- as.vector(c(4,2,1,4,2,5,9.3), mode = “integer”)
  b <- as.vector(c(“we”, “are”, “using”, “vector”, “method”), mode = “character”)
  c <- as.vector(c(1,0,0,1,1,0,1,0), mode = “logical”)
  vector(mode = “integer”, length = 6)
  vector(mode = “logical”, length = 3)

Output:

Note: is.vector(x) will check whether the variable is a vector or not

is.vector(x)
	[1]TRUE
