CHANGES IN canprot 0.1.2 (2019-02-26)
-------------------------------------

- Replace data(canprot) with automatic loading of data when package
  loads, into an environment that is now an exported object ('canprot').

- Because of similar changes in CHNOSZ, we now need library(CHNOSZ) in
  more places in examples and vignettes.

CHANGES IN canprot 0.1.1 (2018-01-18)
-------------------------------------

- New function get_comptab() merges and replaces ZC_nH2O() and CNS(),
  and adds capability to calculate standard molal volumes.

- Add protein length ('nAA') as variable in get_comptab().

- Add 'mfun' argument to get_comptab() to choose median or mean.

- Add 'vars' argument to xsummary() to choose variables to tabulate.

- In pdat_ functions, add =NT tag for datasets involving comparisons
  with normal tissue.

- Use precomputed colors to remove colorspace dependency.

- DESCRIPTION: Add KernSmooth to Suggests to avoid R CMD check error
  (it is needed for smoothScatter() in basis_comparison.Rmd).

CHANGES IN canprot 0.1.0 (2017-06-13)
-------------------------------------

- Add basis_comparison.Rmd and potential_diagrams.Rmd.

- New functions groupplots() to make potential diagrams for groups of
  datasets and mergedplot() to merge those diagrams.

- First release on CRAN.

CHANGES IN canprot 0.0.5 (2017-05-04)
-------------------------------------

- Remove internal setbasis(); use CHNOSZ's basis() instead.

CHANGES IN canprot 0.0.4 (2017-03-19)
-------------------------------------

- New function CNS() calculates proteomic differences of elemental
  abundances per residue.

- Modify diffplot() to accept output from either ZC_nH2O() or CNS().

- Change "AA" and "AA4" in setbasis() to "QEC" and "QEC4"; add "QEC+"
  (basis including H+).

CHANGES IN canprot 0.0.3 (2017-01-01)
-------------------------------------

- New export: get_colors().

- Plot text labels in diffplot().

- Return values in rankplot() and xsummary().

- Change chemical activities in setbasis("AA")
  (use setbasis("AA4") for old ones).

- Move protein expression data to extdata/expression/[condition name]/.

- Add LXM+16 dataset for colorectal cancer.

- Add datasets from 17 studies for pancreatic cancer.

- Add datasets from 20 studies for hypoxia or 3D culture.

- Add datasets from 13 studies for hyperosmotic stress.

CHANGES IN canprot 0.0.2 (2016-07-25)
-------------------------------------

- Add 'updates_file' argument to check_ID() and protcomp().

- Rename stabplot() to rankplot().

- Initial upload to GitHub.

CHANGES IN canprot 0.0.1 (2016-07-16)
-------------------------------------

- Package development began on 2016-07-03, based on code and data in
  Supplemental Information Dataset S1 of Dick, 2016
  (http://doi.org/10.7717/peerj.2238).

- Exported functions (in approximate order of development): "protcomp",
  "check_ID", "get_pdat", "ZC_nH2O", "CLES", "xsummary", "rankdiff",
  "stabplot", "Ehplot", "pdat_CRC", "remove_entries", "diffplot",
  "lapply_canprot".

- Datasets in 'canprot' environment: human_base.Rdata (21006 proteins),
  human_additional.Rdata (71173 proteins), human_extra.csv (72 proteins),
  uniprot_updates.csv (26 proteins).

- Datasets in inst/extdata: AKP+10.csv, BPV+11.csv, JCF+11.csv, JKMF10.csv,
  KKL+12.csv, KWA+14.csv, KYK+12.csv, LPL+16.csv, MCZ+13.csv, MRK+11.csv,
  PHL+16.csv, STK+15.csv, UNS+14.csv, WDO+15.csv, WKP+14.csv, WOD+12.csv,
  WTK+08.csv, XZC+10.csv, YLZ+12.csv, ZYS+10.csv.

- Vignettes: data_sources.Rmd, summary_table.Rmd, stability_plots.Rmd.
