Entering Data

To enter data as a vector in the R Language, we use the combine function i.e. c(). The c() function is a generic function that combines its arguments to form a vector. All arguments are coerced to a common type. To create a numeric vector we pass numbers as arguments to the c() function. To create a character vector we pass the strings or characters as arguments to the c() function.

Syntax: sample_vector <- c( data1, data2, ….. , datan )

where: data1, data2…: determines the numeric values that comprise the vector.

Example: Demonstrating basic character and numeric vectors.

R

# create numeric vector
numeric <- c(1,2,3,4,5)
  
# create character vector
character <- c("geeks", "for", "geeks")
  
# print vectors and their class
print("Character vector:")
character
print("Class:")
class(character)
print("Numeric vector:")
numeric
print("Class:")
class(numeric)

Output:

Character vector:
"geeks" "for"   "geeks"
Class:
"character"
Numeric vector:
1 2 3 4 5
Class:
"numeric"
