Description Usage Arguments Details Value Examples

t_td forces there to be d digits after the decimal for the numeric input x, without messing with the "integer part" of x; t_sd messes with the integer part (i.e. uses significant digits). Both are vectorized over x.

`x` |
numeric to clean; if not numeric, will be coerced |

`d` |
number of trailing digits (for t_td) or significant digits (for t_sd) |

`commas` |
whether to insert commas in the number (the default) |

`except` |
do not modify these positions of the vector |

t_td ("texhelp trailing digits") returns a character vector version of x, rounded or expanded with trailing digits so that there are exactly d digits after the decimal point. That is, rounding is done or 0s are added to the end as needed.

t_sd ("texhelp significant digits") returns a character vector version of x so that there are exactly d significant digits shown. Trailing zeroes are added as needed, to make the point that there are actually d significant digits.

(In most cases you will want to use t_td in order to force a list of numbers to have the same number of trailing digits – this looks better.)

In both functions, commas are added where necessary; turn off with commas=FALSE.

The except parameter is included to make it painless to deal with the common case of an identifying column for which you do not want trailing digits.
