Create a vector called "v1" containing four values, in this order- 2, 9, 3, 4.5.
v1 = c(2, 9, 3, 4.5)
Find the length of v1
length(v1)
Create a vector called "v2" containing four values, in this order- 15, 4, 8, 10
v2 = c(15, 4, 8, 10)
Combine the v1 and v2 vectors into one vector of length 8, assigning the result to v3
v3 = c(v1, v2)
Find the mean of v3
mean(v3)
Extract the third value from v3
v3[3]
