ENHANCEMENTS to SSD for R - version 1.4.3

We simply don't rest!  In the past few weeks we have been hard at work getting the book ready for publication AND we have added some enhancements to SSD for R!

First, to get the newest version of our software, simply click the "Check for Updates" button in the Packages pane of RStudio. You may want to update all your packages, but you will DEFINITELY want to update SSD for R.  Here's what's new:

Trimline() - this function enables you to add a trimmed mean line to an ABplot().  We had this function before, but now when you run the function, the value for the trimmed mean is displayed in the Console.  How does this help you?  It makes labeling your graph really, really easy.  For example, it took me about 30 seconds to produce and completely annotate this graph of a client's crying behavior.



IQRline() - this function enables you to add interquartile range lines to any phase on an ABplot().  Again, we had this function before, but output in the Console makes it really easy to label your graphs quickly.  Here's what this could look like with the same client's crying behavior.


ABstat() - again, the output in the Console makes labeling graphs a snap.  In this case, we added and labeled the median line to the ABplot() above.  Now, we essentially have the middle part of a box plot superimposed on a line graph!


Gindex() - finally, we added some additional information in the output to this effect size function.  Now, we can interpret our findings more easily.



With accepted values displayed in the output, we can see that our desired range, below the regression line, has a calculated value of 0.462, which is indicative of a medium effect.  The graph in the plots pane helps us visualize this clearly.
