format.df: Format a Data Frame or Matrix for LaTeX or HTML

Description

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.

Usage

format.df(x,
          digits, dec=NULL, rdec=NULL, cdec=NULL,
          numeric.dollar=cdot,
          na.blank=FALSE, na.dot=FALSE, blank.dot=FALSE,
          col.just=NULL, cdot=FALSE, dcolumn=FALSE, matrix.sep=' ', 
          scientific=c(-4,4), ...)

Arguments

a matrix (usually numeric) or data frame

digits

causes all values in the table to be formatted to digits significant digits. dec is usually preferred.

dec

If dec is a scalar, all elements of the matrix will be rounded to dec decimal places to the right of the decimal. dec can also be a matrix whose elements correspond to x, for customized rounding of eac

rdec

a vector specifying the number of decimal places to the right for each row (cdec is more commonly used than rdec) A vector rdec must have number of items equal to number of rows of input x. rdec

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 TRUE to use centered dots rather than ordinary periods in numbers.
The output uses a syntax appropriate for latex.

na.blank

Set to TRUE to use blanks rather than NA for missing values.
This usually looks better in latex.

dcolumn

Set to TRUE to use David Carlisle's dcolumn style for
decimal alignment in latex.
Default is FALSE. You will probably want to
use dcolumn if you use rdec, as a column may then c

numeric.dollar

logical, default !dcolumn.  Set to TRUE to place dollar
signs around numeric values when dcolumn=FALSE.  This 
assures that latex will use minus signs rather than hyphens to indicate
negative numbers.  S

na.dot

Set to TRUE to use periods rather than NA for missing
numeric values. 
This works with the sas convention that periods indicate missing values.

blank.dot

Set to TRUE to use periods rather than blanks for missing character values.
This works with the sas convention that periods indicate missing values.

col.just

Input vector col.just must have number of columns equal to
  number of columns of the output matrix.  When NULL, the
  default, the col.just attribute of the result is set to
  "l" for character columns
