[R] How to avoid rounding of matrix elements?

[Tim F Liao]

The signif() function doesn't increase the number 
significant digits beyond the default.  However, if your 
purpose is simply to see more digits (or what was entered), 
a paste() function will do the trick though it will trim the 
trailing zeros.  Other ways?
