Changes in version 0.3.5 (2023-10-06)                  

Fixes

  - sg_apply(dt_prep_sets): add extra "_row<row-number>" string to
    prep_label column of dt_prep_sets input when combining with
    Savitzky-Golay parameter sets. This modification makes sure that
    cartesian products of existing preprocessing sets supplied as input
    are correctly formed with the repeated Savitzky-Golay plans.

                 Changes in version 0.3.4 (2023-10-05)                  

                 Changes in version 0.3.3 (2023-10-05)                  

Fixes

  - failed to commit changes. Keeping entry for reproducibility. The
    intended fix is is in version 0.3.4 (see above).

                 Changes in version 0.3.2 (2023-10-05)                  

Fixes

  - snv_apply(X): add prep_params as list-column with a single-row
    data.table (snv = NA) to the output when X is provided. This makes
    binding outputs to other (pre)processed collections of spectra
    possible without further intervention; also, append_rows = TRUE will
    work with other methods, when output of snv_apply() is used as input
    of other *_apply() functions.

               Changes in version 0.3.1.9000 (2023-10-05)               

Fixes

  - sg_apply(): allow joins of Savitzky-Golay plans and preprocessing
    labels, and then also prepared Savitzky-Golay plans with inputted
    dt_prep_sets, when there is duplicated is. This is the case when
    dt_prep_sets input has already multiple rows (multiple collections)
    of spectra. Now, the desired duplicate joins are explicitly allowed
    by setting allow.cartesian = TRUE for respective data.table joins
    inside the sg_make_dt_prep() helper.

                 Changes in version 0.3.0 (2023-10-05)                  

Features

  - Implement colmean_group_apply() and group label constructor
    ids_apply.R(). This is to apply column means to to spectral
    collections, each by a group label.

                 Changes in version 0.2.1 (2023-09-13)                  

  - patch sg_apply() so that the extra "-snv" that got accidentally
    added to both prep_set and prep_label is not there anymore.

                 Changes in version 0.2.0 (2023-09-13)                  

  - patch sg_apply(), so that it can be run after e.g. snv_apply() (via
    dt_prep_sets input argument).

                 Changes in version 0.1.0 (2023-09-09)                  

Features

  - added snv_apply() to compute the standard normal variate (SNV) of
    spectral collections (#15).
  - added sg_apply() to process spectral collections with Savitzky-Golay
    smoothers with different parameter sets (derivative order, window
    size, polynomial degree).
