I am trying to make an oncoplot with the oncoplot function of the maftools package (version 2.4.0), using R version 4.0.0. Everything is fine as long as I don't try to plot the nonmutated samples. But when I call:

> oncoplot(maftest,removeNonMutated=FALSE)

    Error in top_bar_data[, colnames(numMat), drop = FALSE] : 
      subscript out of bounds

....I get the error message above. My MAF file contains nonmutated samples, having just a name, but otherwise empty. Is there an issue with the format of those nonmutated rows in the MAF file or have I found a bug? I did not experiece this message with a previous version of R/BionConductor and maftools.
