visualize - visualize 4.3.0 - Hotfix - "Seeing is Modern"

CHANGES

• 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 - 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="" 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="" requires one statistic. Please resubmit with stat=yourteststatistic." - 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 "" 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 - 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).
