Corrected the link to cltq() in the main smovie help page.
Create the help file for the package correctly, with alias smovie-package.
Activated 3rd edition of the testthat package
The BWidget Tcl/Tk module is no longer a system requirement for the rpanel package on which smovie depends. rpanel checks whether BWidget is available wen it is required and provides instruction if it is not. This task has been removed from smovie.
In help files and vignettes DOIs are used rather than URLs.
A typo in a section heading in the vignette has been corrected: “simply” becomes “a simple”.
LazyData: TRUE has been removed from DESCRIPTION, because there is no data/ directory in smovie.
Errors in test name strings supplied to testthat::test_that() have been corrected, to avoid CRAN package check ERRORs.
In wws() the gradient of the log-likelihood was unnecessarily labelled with a red “score” when the null value of theta0 is less than the MLE of theta. This has been removed.
In wws(), when model = "norm" the value of mu could not be passed as described. This has been corrected.
In shypo() there was a bug that meant that the plots did not behave as intended when mu0 is not equal to (the default value of) 0. This has been corrected.
In the documentation for shypo() a minor typo at the end of the Details section has been corrected: “based on the current value of n” has been deleted.
In discrete() radio buttons have been added to switch between the version of the the geometric distribution based on the number of trials up to including the first success and the number of failures until the first success.
In discrete() a typo has been corrected in the 4th line of the documentation of the argument distn: “hypergeometric” should have read “negative binomial”.
revdbayes and SuppDists have been demoted from Imports to Suggests. An error is thrown if actions that require either of these packages occurs and that package is not available.New movie: cltq(). Central Limit Theorem for sample quantiles. Illustrates the sampling distribution of the sample quantiles and the central limit theorem for sample quantiles.
New movie: mean_vs_median(). Compares the sampling distributions of the mean and median for random samples from either a standard normal distribution or a standard Student t distribution.

In ett() the sample size n is now allowed to drop to 1 for those cases in which the normalising constants underlying the calculations are finite, such as the exponential, uniform and generalised Pareto distributions. Otherwise, 2 is the smallest allowable value for n.
When the Wald, Wilks and Score tests movie wws() is called from the main menu, via movies() a binomial example is used, so that the differences between the test statistics can be seen.
Adjustments have been made to the wws() movie to ensure that the plot stays completely still during the animations.
The way that objects modified inside the plotting function are saved has been changed to enable two or more panels produced by the same smovie function to operate simultaneously and independently, even if the call is exactly the same.
The argument plot_par in the functions discrete and continuous didn’t work properly. It does now.
Both hscale and vscale may be passed to the main menu function movies to scale the size of the graphics panel horizontal and vertically.
In ett() and clt() the legend position in plots of cdfs has been moved to “topleft” better to avoid overlapping the contents of the plot. The argument leg_cex has been added to enable manual control of the size of the legends.
That smovie requires the R extension BWidget (via its dependence on the package rpanel) is noted in the README file. If BWidget is not installed then a message is given to explain why the smovie functions don’t work.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
