RotMatRF {ODRF}

Create a Projection Matrix: Random Forest (RF)

Description

Create a projection matrix with coefficient 1 and 0 such that the ODRF (ODT) has the same partition variables as the Random Forest (CART).

Usage

RotMatRF(dimX, numProj, catLabel = NULL, ...)

Arguments

dimX

The number of dimensions.

numProj

The number of projection directions (default ceiling(sqrt(dimX))).

catLabel

A category labels of class list in predictors. (default NULL, for details see Examples of ODT)

...

Used to handle superfluous arguments passed in using paramList.

Value

A random matrix to use in running ODT.

• Variable: Variables to be projected.

• Number: Number of projections.

• Coefficient: Coefficients of the projection matrix.
