## Writes a latex formatted table to a file

### Description

Automatically generates a latex formatted table from the matrix x Controls rounding, alignment, etc, etc

### Usage

    ## S3 method for class 'table'
    latex(x, file=as.character(substitute(x)),
    	rowlabel=file, rowlabel.just="l", cgroup, n.cgroup, rgroup, n.rgroup=NULL,
    	digits, dec, rdec, cdec, append=FALSE, dcolumn=FALSE, cdot=FALSE,
    	longtable=FALSE, table.env=TRUE, lines.page=40, caption, caption.lot,
    	label=file, double.slash=FALSE,...)

### Arguments

`x` | A matrix `x` with dimnames
`file` | Name of output `file` (.tex will be added)
`rowlabel` | 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.
`rowlabel.just` | 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.
`cgroup` | a vector of character strings defining major column headings. The default is to have none.
`n.cgroup` | 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.
`rgroup` | 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.
`n.rgroup` | 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.
`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 each element.
`rdec` | a vector specifying the number of decimal places to the right for each row (‘cdec’ is more commonly used than ‘rdec’)
`cdec` | a vector specifying the number of decimal places for each column
`append` | defaults to ‘F’. Set to ‘T’ to append output to an existing file.

`dcolumn`

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.

`cdot` | Set to ‘T’ to use centered dots rather than ordinary periods in numbers.
`longtable` | 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.
`table.env` | 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’.
`lines.page` | 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.
`caption` | a text string to use as a caption to print at the top of the first page of the table. Default is no caption.
`caption.lot` | a text string representing a short caption to be used in the "List of Tables". By default, LaTeX will use ‘caption’.
`label` | 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.
`double.slash` | 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.
`...` | other optional arguments
