rebase_origin(x)

Arguments

n	[numeric(1): NULL] The index of the new base year.

Value

Returns a vector with the same class and attributes as the input vector.

Examples

x <- 3:10

# New base  would be 5
rebase(x, 5)
#> [1] 0.4285714 0.5714286 0.7142857 0.8571429 1.0000000 1.1428571 1.2857143
#> [8] 1.4285714

# Or the origin
rebase_origin(x)
#> [1] 1.000000 1.333333 1.666667 2.000000 2.333333 2.666667 3.000000 3.333333

# Fro the base to be 100 or 0 then:
rebase(x, 5)*100
#> [1]  42.85714  57.14286  71.42857  85.71429 100.00000 114.28571 128.57143
#> [8] 142.85714
rebase(x, 5) - 1
#> [1] -0.5714286 -0.4285714 -0.2857143 -0.1428571  0.0000000  0.1428571  0.2857143
#> [8]  0.4285714
