A matrix x with dimnames
Name of output file (.tex will be added)
If `x' has row dimnames, rowlabel is a character string containing the column heading for the row dimnames. The default is the name of the argument for x.
If `x' has row dimnames, specifies the justification for printing them. Possible values are ` "l", "r", "c"'. The heading (`rowlabel') itself is left justified if `rowlabel.just="l"', otherwise it is centered.
a vector of character strings defining major column headings. The default is to have none.
a vector containing the number of columns for which each element in cgroup is a heading. For example, specify `cgroup= c("Major 1","Major 2")', `n.cgroup=c(3,3)' if "Major 1" is to span columns 1-3 and "Major 2" is to span columns 4-6. `rowlabel' does not count in the column numbers. You can omit `n.cgroup' if all groups have the same number of columns.
a vector of character strings containing headings for row groups. `n.rgroup' must be present when `rgroup' is given. The first `n.rgroup[1]' rows are sectioned off and `rgroup[1]' is used as a bold heading for them. The usual row dimnames (which must be present if `rgroup' is) are indented. The next `n.rgroup[2]' rows are treated likewise, etc.
integer vector giving the number of rows in each grouping. If `rgroup' is not specified, `n.rgroup' is just used to divide off blocks of rows by horizontal lines. If `rgroup' is given but `n.rgroup' is omitted, `n.rgroup' will default so that each row group contains the same number of rows.
causes all values in the table to be formatted to `digits' significant digits. `dec' is usually preferred.
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 each element.
a vector specifying the number of decimal places to the right for each row (`cdec' is more commonly used than `rdec')
a vector specifying the number of decimal places for each column
defaults to `F'. Set to `T' to append output to an existing file.
Set to `T' to use David Carlisles `dcolumn' style for decimal alignment. Default is `F', which aligns columns of numbers by changing leading blanks to "~", the LaTeX space-holder. 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.
Set to `T' to use centered dots rather than ordinary periods in numbers.
Set to `T' to use David Carlisles LaTeX `longtable' style, allowing long tables to be split over multiple pages with headers repeated on each page.
Set `table.env=FALSE' to suppress enclosing the table in a LaTeX `table' environment. `table.env' only applies when `longtable=FALSE'. You may not specify a `caption' if `table.env=FALSE'.
Applies if `longtable=TRUE'. No more than `lines.page' lines in the body of a table will be placed on a single page. Page breaks will only occur at `rgroup' boundaries.
a text string to use as a caption to print at the top of the first page of the table. Default is no caption.
a text string representing a short caption to be used in the "List of Tables". By default, LaTeX will use `caption'.
a text string representing a symbolic label for the table for referencing with the LaTex `\ref{label}' command. The default is `file'. `label' is only used if `caption' is given.
set to `T' to output `\' as `\\' in LaTeX commands. Useful when you are reading the output file back into an S vector for later output.
