combinequark: Combine the results from the quark function

Description Usage Arguments Value Author(s) See Also Examples

View source: R/quark.R

Description

This function builds upon the quark function to provide a final dataset comprised of the original dataset provided to quark and enough principal components to be able to account for a certain level of variance in the data.

Usage

1
combinequark(quark, percent)

Arguments

quark

Provide the quark object that was returned. It should be a list of objects. Make sure to include it in its entirety.

percent

Provide a percentage of variance that you would like to have explained. That many components (columns) will be extracted and kept with the output dataset. Enter this variable as a number WITHOUT a percentage sign.

Value

The output of this function is the original dataset used in quark combined with enough principal component scores to be able to account for the amount of variance that was requested.
