                        Changes in version 4.2.0                        

  - A big thanks to Psychology Drs. Sharon Klinkenberg of the University
    of Amsterdam, who reported many of the bugs that were addressed in
    this release!

MINOR CHANGES

  - Error handling has been modified such that when improper parameters
    are supplied in the following scenarios the program will not render
    a graph and provide log out as to why the graph did not render:
    
      - Supply 1 statistic for a bounded or tails condition now stops
        the program from generating a graph. In the console, the user
        will receive:
    
    "Supplied stat length < 2 and section="<bounded,tails>" requires two
    statistics. Please resubmit with parameter stat=c(lower,upper)."
    
      - Supply 2 statistics but do not request a bounded or tails
        condition now stops the program from generating a graph. In the
        console, users will receive:
    
    "Supplied stat length > 1 and section="<lower,upper>" requires one
    statistic. Please resubmit with stat=your_test_statistic."
    
      - Supply only 1 strict value for discrete distributions and
        request bounded or tails, then the strict value will apply to
        both ends. In the console, users will receive:
    
    "Supplied strict length < 2, setting inequalities to "<strict, equal
    to>" inequality."

  - A warning is now issued when requesting tails option for a
    nonsymmetric distribution.

BUG FIXES

  - Area for the F distribution should now render more reliably
    underneath the probability density function plot.
  - F Distribution correctly renders F-Statistic instead of T-Statistic.
  - F Distribution's parameters (df1,df2) are now correctly rendered.
  - If a test statistic for a continuous distribution begins above or
    below the graph's bounds, then the graph will render without a
    highlighted area.
  - All graphs involving nonsymmertric distributions now begin on the
    x-axis at 0.

                        Changes in version 4.1.0                        

BUG FIX

  - Documentation should no longer disappear off screen.

                        Changes in version 4.0.0                        

NEW

  - Two tail evaluations for both continuous and discrete distributions!
  - Highlighted shading in continuous distributions!
  - Start and End markers for test statistic(s) on x-axis!

DOCUMENTATION

  - Updated visualize. functions to account for new section request.

                        Changes in version 3.0.0                        

NEW

  - Evaluate probabilities with strict inequalities!

MINOR CHANGES

  - Rewrote sections to increase efficiency and reliability.

                        Changes in version 2.2.0                        

BUG FIX

  - Corrects rendering issue with supplied stat not meeting certain
    criteria.

                        Changes in version 2.1.0                        

BUG FIXES

  - Corrects minor graphing labels.
  - Revised error handling.

                        Changes in version 2.0.0                        

NEW

    Normal, Logistic, T, and Wilcox.

                        Changes in version 1.0.0                        

NEW

  - Graph the PDF or PMF of a probability function and determine the
    probability enclosed.
  - See characteristics of the distribution requested (Parameters, Mean,
    and Variance).
  - Supported Continuous Distributions: Chi-squared, beta, gamma,
    exponential, uniform, and normal.
  - Supported Discrete Distributions: Geometric, binomial, poisson,
    hypergeometric, and negative binomial.

THANKS

  - Visualize was made as an independent study project to learn about
    creating r-packages and explore probability distributions that was
    approved and mentored by Statistics Professor Jeffrey A Douglas at
    the University of Illinois at Urbana-Champaign (UIUC).
