                 Changes in version 1.3.6 (2022-06-15)                  

1.  Fix minor issue of item values at help files for OS
    "-linux-x86_64-debian-clang", "r-devel-linux-x86_64-debian-gcc"

                 Changes in version 1.3.5 (2019-06-28)                  

New functions added for knee point estimation

  - check_curve() checks a curve for its convexity type
  - uik() finds the UIK estimation for elbow or knee point of a curve
  - d2uik() performs UIK method on the approximation of second order
    derivatives

The Unit Invariant Knee (UIK) estimator is described in article:

    (UIK) As an Objective Choice for Elbow Point in Multivariate Data
    Analysis Techniques. Available at SSRN:
    http://dx.doi.org/10.2139/ssrn.3043076

Vignettes added for the package

Install the inflection package and then read vignettes:

  - vignette('inflection', package ='inflection') an introductory
    vignette
  - vignette('inflectionDevelopingMethods', package ='inflection')
    reproduction of results for article:
      - Demetris T. Christopoulos (2014). Developing methods for
        identifying the inflection point of a convex/concave curve.
        arXiv:1206.5478v2 [math.NA]. https://arxiv.org/pdf/1206.5478v2
  - vignette('inflectionMissionImpossible', package ='inflection') a
    vignette for ‘impossible’ missions

Minor changes

Remove the option to plot in two separate pdfs ‘ese_iterations.pdf’,
‘ede_iterations.pdf’ from findipiterplot() and open new plot windows
instead of saving files.

                  Changes in version 1.3 (2017-05-13)                   

Use of parallel computing under request (doparallel=TRUE) for the functions:

  - ese()

  - bese()

  - findiplist()

  - findipiterplot()

Repair of function findipiterplot()

1.  Fix bugs in calling the function
2.  Remove indirect methods CRESE, CREDE due to their limited
    functionality
3.  Plot in two separate pdfs ‘ese_iterations.pdf’ and
    ‘ede_iterations.pdf’
4.  Check for the existence of sufficient number of results before
    creating confidence intervals

                  Changes in version 1.2 (2016-06-10)                   

1.  The function eixf(x, y, f, i) was removed as not essentially
    necessary
2.  New functions with self declaring names were added:

  - ese(x,y,index)
  - bese(x,y,index)
  - ede(x,y,index)
  - edeci(x,y,index)
  - bede(x,y,index) All functions require length(x)>=4 in order to
    create numeric output

1.  The function findipiterplot(x,y,index) was improved and became
    findipiterplot(x, y, index, plots = TRUE, crossrun = FALSE, ci =
    FALSE)
2.  Changes in NAMESPACE
3.  Reference to new paper:
