Access TRMF factors

Description

This function returns the factors (Xm, Fm) from a trained TRMF object

Usage

## S3 method for class 'TRMF'
components(object, XorF = c("Xm","Fm"), ...)

Arguments

Details

Returns the matrix factors. Could also use object$Factors$Xm, object$Factors$Fm . If matrix normalization was used in create_TRMF, Xm%*%Fm could look much different than the input data matrix.

Value

A matrix.

Examples

# create test data
xm = poly(x = (-10:10)/10,degree=4)
fm = matrix(rnorm(40),4,10)
Am = xm%*%fm+rnorm(210,0,.2)

# create model
obj = create_TRMF(Am)
out = train(obj)
plot(out)
components(out,"Xm")
