Transform data using the Box-Cox transformation with parameter lambda interpolated between start and end value.

1	tBoxCox(x, lambda0, lambda1 = lambda0, t, when, p)

`x`	numerical vector.
`lambda0`	numeric, starting value of parameter lambda.
`lambda1`	numeric, end value of parameter lambda.
`t`	numeric, homotopy parameter, limited between 0 and 1. This parameter can be considered as fraction of animation duration time.
`when`	numeric vector. This parameter controls the times of: entrance, exit, start of movement and, end of movement.
`p`	numeric, homotopy power parameter. Defaults to 1.

numerical vector, Box-Cox transformed values for current interpolated value of lambda.
