format.df | R Documentation |

`format.df`

does appropriate rounding and decimal alignment, and outputs
a character matrix containing the formatted data. If `x`

is a
`data.frame`

, then do each component separately.
If `x`

is a matrix, but not a data.frame, make it a data.frame
with individual components for the columns.
If a component `x$x`

is a matrix, then do all columns the same.

```
format.df(x, digits, dec=NULL, rdec=NULL, cdec=NULL,
numeric.dollar=!dcolumn, na.blank=FALSE, na.dot=FALSE,
blank.dot=FALSE, col.just=NULL, cdot=FALSE,
dcolumn=FALSE, matrix.sep=' ', scientific=c(-4,4),
math.row.names=FALSE, already.math.row.names=FALSE,
math.col.names=FALSE, already.math.col.names=FALSE,
double.slash=FALSE, format.Date="%m/%d/%Y",
format.POSIXt="%m/%d/%Y %H:%M:%OS", ...)
```

`x` |
a matrix (usually numeric) or data frame |

`digits` |
causes all values in the table to be formatted to |

`dec` |
If |

`rdec` |
a vector specifying the number of decimal places to the right for each row
( |

`cdec` |
a vector specifying the number of decimal places for each column. The vector must have number of items equal to number of columns or components of input x. |

`cdot` |
Set to |

`na.blank` |
Set to |

`dcolumn` |
Set to |

`numeric.dollar` |
logical, default |

`math.row.names` |
logical, set true to place dollar signs around the row names. |

`already.math.row.names` |
set to |

`math.col.names` |
logical, set true to place dollar signs around the column names. |

`already.math.col.names` |
set to |

`na.dot` |
Set to |

`blank.dot` |
Set to |

`col.just` |
Input vector |

`matrix.sep` |
When |

`scientific` |
specifies ranges of exponents (or a logical vector) specifying values
not to convert to scientific notation. See |

`double.slash` |
should escaping backslashes be themselves escaped. |

`format.Date` |
String used to format objects of the Date class. |

`format.POSIXt` |
String used to format objects of the POSIXt class. |

`...` |
other arguments are accepted and passed to |

a character matrix with character images of properly rounded `x`

.
Matrix components of input `x`

are now just sets of columns of
character matrix.
Object attribute`"col.just"`

repeats the value of the argument `col.just`

when provided,
otherwise, it includes the recommended justification for columns of output.
See the discussion of the argument `col.just`

.
The default justification is ‘l’ for characters and factors,
‘r’ for numeric.
When `dcolumn==TRUE`

, numerics will have ‘.’ as the justification character.
