We are releasing a small patch for stats4ROI with some new features and some minor bug fixes.
You can download it here:
(You can read the complete stats4ROI Changelog here)
- Changed two-tailed option in sample size and power calculations to "Not equal to null"
- Added one sample exact power and sample size calculations for Pearson r
- Added Greek letters to power curves
- Improvement in the power curves graphics
- Known issues:
- datamods no longer will load .dat files with only one column - this is a limitation in the packages it uses. A fix is in the works. A workaround is to save that as a .txt file or just cut and paste the data.
- If you run the app from RStudio and you have clicked on a line number to add a breakpoint, it will take a long time to load the app - this is due to RStudio functions that take 10+ seconds to load. Once they are loaded, it does not affect the app. Consider loading via RGui if this is an annoyance since it loads immediately there. This does not happen if you avoid adding a breakpoint that way.
- Lin-Mudholkar test fails due to breaking the function when the correlation is 1 (lolcat issue)
- No button on MVP(E) or Mann-Whitney-U 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. This seems to be built into ggh4x.
