title: Print R data frame one line per row
body: <p>When using print to print data frames I find that it stops at some width, a bit short of 80 characters, and prints only those columns that can fit. Then it proceeds to print the next so-many columns.</p>
  <p>Is is possible to get it to print a whole row, regardless of how wide, without newlines or dots, to the output?</p>
