Projection to pls and then re-construction

Description

Projects spectra onto a PLS space and then reconstructs it back.

Usage

reconstruction_error(x, 
                            projection_mat, 
                            xloadings, 
                            scale, 
                            Xcenter, 
                            Xscale, 
                            scale_back = FALSE)

Arguments

`x`	a matrix to project.
`projection_mat`	the projection matrix generated by the `opls_get_basics` function.
`xloadings`	the loadings matrix generated by the `opls_get_basics` function.
`scale`	logical indicating if scaling is required
`Xcenter`	a matrix of one row with the centering values
`Xscale`	a matrix of one row with the scaling values
`scale_back`	compute the reconstruction error after de-centering the data and de-scaling it.
