I read a tab-delimited text file into R.  Except for the first 
column, it is all integer-valued.  I get the following message when 
trying to plot using hexplom.

Error in grid.Call.graphics("L_downviewport", name$name, strict) :
   Viewport 'plot1.panel.1.1.off.vp' was not found

(pairs works fine with these data)
