`make_loading` method takes the loading matrix obtained by a mixOmixs package and fold them into two-dimensional matrix

## Arguments

- floadings
a numeric matrix with foreign loadings. With variables in columns and eigenvalues as rows.

- time
a vector of length two with the time range of the chromatographic run

- mod_time
the modulation time of the second dimension.

- acq_rate
the acquisition rate of the mass analyzer. The acquisition rate is printed when read_chrom function is performed

## Details

We strongly recommend to use the plsda function in the mixOmics
package to perform partial least squares-discriminant analysis. The result
of this model is a list containing a loading matrix.
The method retrieves a matrix A with *m* and *n* dimensions.
Where *m* is the eigenvalues and *n*
is the number of loadings which the model returns.
