transform_data: Transform data matrix function
In angy89/hyQSAR: Hybrid QSAR model

This function transform data based on the type of transfromation

1 2	transform_data(X, type.transformation = "abs.alpha.power", power = 1, cost = 3, bb = 2)

`X`	is the matrix of the dataset with samples on the rows and features on the column
`type.transformation`	is a string indicating the type of transformation to be performed at the data before fitting the model. It can be one of the following: "none","abs","abs.alpha.power","mul","log.abs","log.abs.alpha.power"; none is the default parameter.
`power`	is a numeric power to be used in the abs.alpha.power transformation. Default is 1.
