This function can be used to create a proper trans object that encapsulates a power transformation (x^n).

power_trans(n)

Arguments

n

The degree of the power transformation

Value

A trans object

Examples

# Power of 5 transformations trans <- power_trans(2) trans$transform(1:10)
#> [1] 1 4 9 16 25 36 49 64 81 100
# Cubic root transformation trans <- power_trans(1 / 3) trans$transform(1:10)
#> [1] 1.000000 1.259921 1.442250 1.587401 1.709976 1.817121 1.912931 2.000000 #> [9] 2.080084 2.154435
# Use it in a plot ggplot() + geom_line(aes(x = 1:10, y = 1:10)) + scale_x_continuous(trans = power_trans(2), expand = c(0, 1))
