Unfortunately GenVisR cannot accept VCF files at this time, for now the best approach will be to set the
fileType param to "custom", you will then be able to provide a data frame with the required columns "sample", "gene", "variant_class". You will also need to fill in the parameter "variant_class_order" which takes a character vector specifying the order preference for each variant class. For example if you had both a missense and nonsense mutation for the same gene/sample the one plotted would depend on the "variant_class_order" param.
There is a vignette specific to the waterfall function here as well that you might find usefull.
