The function c is a widely used function to combine values into a vector or a list. The default method combines its arguments to form a vector. All arguments are coerced to a common type which is the type of the returned value, and all attributes except names are removed.
The basic usage of c function is written in the exercise.
# Using c function to combine two vectors
c(1,7:9)
# It can be used to combine multiple types of vectors
c(1:5, 10.5, "next")
# Assign "University of Alabama" to x and Assign "Educational Psychology" to y
x <-
y <-
# Combine x and y into z
z <-
