   force: logical; if true, the 'dimnames' are even removed from
          'data.frame's. _This argument is currently *experimental* and

     ## Answering a question on R-help (14 Oct 1999):
     col3 <- 750+ 100*rt(1500, df = 3)
     breaks <- factor(cut(col3,breaks=360+5*(0:155)))
     z <- table(breaks)
     z[1:5] # The names are larger than the data ...
     barplot(unname(z), axes= FALSE)
