`plot.tune` documentation contains two `plot.tune.splsda` methods

[Max-Bladen]

Within the documentation for the plot.tune() function, there are two methods which describe the plot.tune.splsda() function. In the S3methods-plot.tune.R file, there is the original plot.tune.splsda(). However, there is also the plot.tune.spls1() function. After plot.tune.splsda() is defined, it is set to:

plot.tune.splsda <- plot.tune.spls1 (line 648).

Upon brief exploration, the plot.tune.splsda() function is not used. This will be explored further and confirmed. If so, then potentially removing the original plot.tune.splsda() will be for the best.
