ranomForestSRC::plot.variable not behaving as expected

[harrisonwsmith]

I am attempting to work through the "Random Forests for Regression" vignette, however I have run into an issue near the end when generating partial coplot data for a contour plot. Rather than returning 50 unique coplots for each specific value of rm, the coplots are all identical. The result is that the contour plot only has contours for predicted y values from one x variable, making it just a 3D representation of a single variable co-plot.

In a previous version of the "Random Forests for Regression" vignette this did not appear to be an issue (see output image below)

However, in the updated version of the vignette, the issue has appeared:

Perhaps an update in the plot.variable() function have altered how these codes perform?

Certainly seems to be a plot.variable issue. Though I still have some digging to do to correct this. It will also fail in the release currently being reviewed for CRAN.

Escalated this to randomForestSRC team kogalur/randomForestSRC#339

plot.variable has been deprecated (possibly?). Will need to rewrite the ggPartial methods to take advantage of the partial.rfsrc method to restore previous behavior.
