Rounds numbers to always have the specified number of decimal digits, rather than R's "greedy" most-compact rounding convention. Includes optional "<0.0..." override adequate for representing small p-values.

R's standard round
utility rounds to at *most* the number of digits specified. When the number happens to round more "compactly", it rounds to fewer digits. Thus, for example, 'round(4.03,digits=2)' yields 4 as an answer. This is undesirable when trying to format a table, e.g., for publication.
niceRound
solves this problem by wrapping a format
call around the round
call. The result will always have 'digits' decimal digits. In addition, since reporting p-values always involves rounding, if the argument 'plurb' is TRUE
, then values below the rounding thresholds will be represented using the "less than" convention. For example, with digits=3
and plurb=TRUE
, the number 0.0004 will be represented as <0.001
.
