(ROIstat Changelog)

  • Improved the Shapiro-Wilk test for exponentiality by using a modified function from the exptest package, which uses a Monte Carlo simulation to calculate the p-value instead of using a lookup table. This package does not need to be installed.
  • Improved the histograms in EDA. New features:
    • Exploration where multiple groups are being compared (e.g. different columns or different factors) are now plotted on a single grid graph. You can have the data all on the same axis or let the axis adjust for each graph.
    • Sample sizes are now included on the histogram
    • The graphs can be downloaded in a variety of publish-ready formats
    • A lot less code making it easier to maintain
  • Improved the boxplots in EDA. New features:
    • The graphs can be downloaded in a variety of publish-ready formats
  • Bug Fixes
    • Fixed typo on popup for A-D exponential test
    • The A-D test for exponentiality used in the app fails if there is a zero in the data or if the origin is greater than zero. We now exclude zeroes from the data set for this test and give a checkbox option to make the minimum the minimum in the dataset.
    • Fixed "object 'd' not found" in EDA when using factor with names as levels
    • Additional spurious messages were taken out
    • Refined to avoid console warning messages from ggplot about deprecating aes_string
  • Known issues:
    • Long pause once ROIstat loads, disabled blog links to help
    • Font Awesome errors at startup is due to shinywidgets
    • Lin-Mudholkar test fails due to breaking the function when the correlation is 1 (lolcat issue)
    • Reported problem with use data one and two sample tests, object x2 not found (can't replicate)
    • No button on MVP(E) test to stop early - may be added in the future
    • The density plot x-axis for the exponential will start at zero even if the minimum is above that
