A want a barplot without the labels beneath the bars:

I have tried names.arg = "", but it returns an error:

Error in barplot.default(stats::xtabs(mf, addNA = TRUE), horiz = horiz,  : 
  incorrect number of names

I understand that the length of names.arg should correspond to the number of bars, but I don’t want to calculate that and create something like names.arg = rep("", 50).

How can I suppress those labels?
