• Added alias to read_chroms for reading mzxml files with RaMS.
• Added precision argument to call_rainbow to control number of digits "mz" values are rounded to. (Also changed default behavior so values are rounded to one decimal by default).
• Fixed bug in read_shimadzu_lcd on Windows due to issue with passing escaped paths to Python.
• Updated documentation of various functions.

v0.5.0

chromConverter 0.5.0

New features

• Added support for parallel processing through pbapply package. (Note: The pbapply package must be manually installed to enable parallel processing).
• Added internal parser for 'Agilent Chemstation' version 31 files (through read_chemstation_uv function).
• Added support for 'Agilent OpenLab' version 131 files through internal parser.
• Added preliminary support for reading 'Agilent' (.dx) files (through read_agilentdx function).
• Added support for reading 'Chemstation' REPORT files.
• Added parser for Shimadzu .lcd files through the read_shimadzu_lcd function. Only the PDA stream (not MS) is currently supported.
• Added read_peaklist function for reading peak lists. Currently 'Agilent Chemstation' and 'Shimadzu ASCII' formats are supported.
• Added verbose argument to control console output for external parsers ('OpenChrom' and 'ThermoRawFileParser').

Other Improvements

• Improved automatic filetype detection by read_chroms.
• Refactored read_thermoraw function to simplify paths.
• The thermoraw and openchrom parsers now use a proper temp directory if an export directory is not specified through the path_out argument.
• Re-factored reshape_chroms, speeding up conversion from wide to long format.
• Added additional tests, attaining 82% test coverage.
• Changed default openchrom export format to mzml.
• Minor changes to some metadata fields to better standardize results across different file formats and parsers.

v0.4.3

chromConverter 0.4.3

chromConverter 0.4.2

• Added support for parsing "Waters" ascii (.arw) PDA files.

v0.4.2

chromConverter 0.4.2

Added support for parsing "Waters" ascii (.arw) PDA files.

v0.4.1

chromConverter 0.4.1

New features

• Added support for "Chemstation" UV (.ch) files (version 30).

Minor improvements

• Updated read_chromeleon to better deal with comma decimal separators in metadata.
• Updated read_chromeleon to deal with more datetime formats.
• Updated read_chromeleon to deal with unicode microliters.
• Added tests for rainbow parser and read_chemstation_ch.

Bug fixes

• Fixed bug preventing compilation of PDF manual.
• Fixed new bug causing failure to correctly read names of chemstation files from .D directory.

v0.4.0

chromConverter 0.4.0

New features

• Added parser for ANDI chrom cdf files through the read_cdf function.
• Added parser for 'Lumex' .mdf files through the read_mdf function.
• Added additional options for file exports. New options for writing
  chemstation_csv (utf-16) and ANDI chrom cdf files through read_chroms.
• Added preliminary support for automatic filetype detection by read_chroms when providing direct paths to files (i.e. when find_files == FALSE).
• Added read_varian_peaklist function for reading peak lists from 'Varian MS Workstation'.

Other improvements and bug fixes:

• Added wide and long data_format options for 2D data, such that the wide format option writes retention times as rownames of the matrix or data.frame. while the long format writes retention times as the first column of the object.
• Updated configure_openchrom for better discovery of 'OpenChrom' path and added path argument for directly specifying the path to 'OpenChrom'.
• Slightly restructured metadata fields. Added source_file field to track
  data origin.
• Standardized datetime stamps so they are always converted to POSIXct format.
• Now use fs package for parsing paths, eliminating buggy check_paths function.
• Fixed bug causing sloppy 'Chemstation' FID metadata.
• Fixed bug that caused padding of 'Chemstation 130' files with extra zeros.
• Added additional tests.
