unused arguments for waterfall

[zpingfeng]

I have been testing the package with the example data based on manual ("http://genomedata.org/gen-viz-workshop/GenVisR/), but got error messages "unused arguments (mutationData, fileType = "Custom", variant_class_order = mutation_priority)" or "unused arguments (inputData, fileType = "Custom", variant_class_order = most_deleterious, mainXlabel = TRUE, out = "grob")" . I have tried to install the package either with BiocManager and devtools::install_github("griffithlab/GenVisR")
