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=cdot,
na.blank=FALSE, na.dot=FALSE, blank.dot=FALSE,
col.just=NULL, cdot=FALSE, dcolumn=FALSE, matrix.sep=' ',
scientific=c(-4,4), ...)
digits significant
digits.
dec is usually preferred.
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 each element.
A matrix
dec must have number of columns equal to number of columns
of input
x.
A scalar
dec is expanded to a vector
cdec with number of
items equal to number of columns of input
x.
cdec is more commonly used than
rdec)
A vector
rdec must have number of items equal to number of rows of input
x.
rdec is expanded to matrix
dec.
TRUE to use centered dots rather than ordinary periods in numbers.
The output uses a syntax appropriate for
latex.
TRUE to use blanks rather than
NA for missing values.
This usually looks better in
latex.
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 contain varying
number of places to the right of the decimal.
dcolumn can line up
all such numbers on the decimal point, with integer values right
justified at the decimal point location of numbers that actually
contain decimal places. When you use
dcolumn=TRUE,
numeric.dollar is set by default to
FALSE. When you use
dcolumn=TRUE, the
"style" element is set to
"dcolumn" as the
latex
\usepackage
must reference
[dcolumn].
The three files
dcolumn.sty,
newarray.sty, and
array.sty will
need to be in a directory in your
$TEXINPUTS path.
When you use
dcolumn=TRUE,
numeric.dollar should be set to
FALSE.
!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. Set to
FALSE when
dcolumn=TRUE, as
dcolumn.sty automatically uses minus signs.
TRUE to use periods rather than
NA for missing
numeric values.
This works with the
sas convention that periods indicate missing values.
TRUE to use periods rather than blanks for missing character values.
This works with the
sas convention that periods indicate missing values.
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 and to
"r" for numeric
columns. The user can override the default by an argument vector
whose length is equal to the number of columns of the result matrix.
When
format.df is called by
latex.default, the
col.just is used as the
cols argument to the
\tabular environment and the letters
"l",
"r",
and
"c" are valid values. When
format.df is called by
sas, the
col.just is used to determine whether a
$ is needed on the
input line of the
sysin file,
and the letters
"l" and
"r" are valid values.
x is a data frame containing a matrix, so that new column names
are constructed from the name of the matrix object and the names of
the individual columns of the matrix,
matrix.sep specifies the
character to use to separate object names from individual column
names.

arguments are passed to the
print function.
x.
Matrix components of input
x are now just sets of columns of
character matrix.
attr(,col.just)
repeats the input
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.
