visualize 4.5.0 - Hotfix - “Seeing is Greek”

CRAN release: 2023-11-13

CHANGES

  • Removed unicode to display variables and inequalities per CRAN request.
  • Increased the required R version to v4.0.0.
  • Switched deployment from Travis to GitHub Actions

visualize 4.4.0 - Hotfix - “Seeing is Refreshing”

CRAN release: 2020-01-08

CHANGES

  • Updated package structure to reflect modern practices (#9)
  • Switched documentation to use markdown (#9).
  • Improved the README.Rmd file with new examples (#10).

visualize 4.3.0 - Hotfix - “Seeing is Modern”

CRAN release: 2017-04-27

CHANGES

  • Switched visualize.distribution from being made on library load to being an internal data set stored in sysdata.rda with build files stored in data-raw (#1)
  • Switched documentation from Rd over to roxygen2 using Rd2roxygen (#2)

MINOR CHANGES

  • Switched NEWS to NEWS.md to take advantage of Markdown formatting. (#5)
  • Switched README to use README.Rmd, which generates README.md. (#4)
  • Added links to GitHub repository in DESCRIPTION file

BUG FIX

  • Corrected outstanding CRAN checks related to malformed DESCRIPTION file and need to import functions (#3)

visualize 4.2.0 - Hotfix - “Seeing is Educational”

  • 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.

visualize 4.1.0 - Hotfix - “Seeing is Windowed”

BUG FIX

  • Documentation should no longer disappear off screen.

visualize 4.0.0 - Live Update - “Seeing is Split”

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.

visualize 3.0.0 - Live Update - “Seeing is Strict”

NEW

  • Evaluate probabilities with strict inequalities!

MINOR CHANGES

  • Rewrote sections to increase efficiency and reliability.

visualize 2.2.0 - Hotfix - “Seeing is Correct”

BUG FIX

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

visualize 2.1.0 - Hotfix - “Seeing is Off”

BUG FIXES

  • Corrects minor graphing labels.
  • Revised error handling.

visualize 2.0.0 - Live Update - “Seeing is Believing”

NEW

  • Support for the following Continuous Distributions: Cauchy, F, Log Normal, Logistic, T, and Wilcox.
  • Bar graph rendering for discrete probability distributions.

MINOR CHANGES

  • Rewritten Distribution Wrapper

visualize 1.0.0 - Live Update - “Seeing is Magic”

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).
