Changes in version 1.1.0 (2025-11-25)                  

This is a minor release adding new additional capabilities and providing
some improvements and bug fixes.

Bug fixes

  - Fixes erros in 'align()' caused if all peaks found are above the
    given threshold, THR.

  - Inconsequencial warnings are suppressed in 'align()'.

  - Modification to the color scale ledgend for data of various scales.

Improvements

  - 'align()' has two additional optional inputs: use_ref_peak and
    ref_peak. Previously, 'align()' assumed the presense of toluene
    (present with themal desorption tubes using Tenax TA sorbent
    material). For users that do not have toluene present, a different
    initial reference m/z value can be input for ref_peak to provide an
    initial shift to the data for alignment. Alternatively, the boolean
    use_ref_peak can be set to FALSE to skip the initial shift to a
    reference peak completely.

  - 'plot_chr()' has two additional option inputs: xlab and ylab. This
    allows modification of the axes labeling on the hoizontal (x) and
    vertical (x) axis.

  - 'plot_peak()' has two additional option inputs: xlab and ylab. This
    allows modification of the axes labeling on the hoizontal (x) and
    vertical (x) axis.

  - 'batch_preprocess()' now has three addtional optional inputs:
    do_align, use_ref_peak, and ref_peak. do_align allows the user to
    change a boolean to skip alignment of the given list of files to
    preprocess if alignment is not necessary. It also includes the two
    new inputs use_ref_peak and ref_peak for 'align()'.

  - 'extract_data()' has been modified to address irregularly shaped
    data. If the last column of data is incomplete (not a full
    modulation period), this data is now removed to allow plotting and
    analysis.

  - Addtional commenting added to 'align()' for code organiziation and
    understandablility.

New capabilities

  - New function 'batch_extract()' which extracts data from all CFD
    files in a given folder path, using the methods of 'extract_data()'.
    Resulting data frames are returned in a list.

  - New function 'TIC_integrate()' allows the user to integrate the area
    under the entire TIC curve. Previously area could only be calculated
    for a given peak. The user may also indicate starting and ending
    times for the region of integration.

                 Changes in version 1.0.1 (2024-01-22)                  

This is a small release, adding vignette to the initial package
submission, 1.0.0.
