Convert an array of numbers or mathematical expressions into an
xtableMatharray
object so it can be printed. A convenience
function to enable the printing of arrays in mathematical expressions
in LaTeX
 (x, = , = , = ,
= , = , auto = , )

x 
A numeric or character matrix.

caption 
Character vector of length 1 or 2 containing the
table's caption or title. If length is 2, the second item is the
"short caption" used when LaTeX generates a "List of Tables". Set to
NULL to suppress the caption. Default value is NULL .
Included here only for consistency with xtable methods. Not
expected to be of use.

label 
Character vector of length 1 containing the LaTeX
label. Set to NULL to suppress the label.
Default value is NULL .

align 
Character vector of length equal to the number of columns
of the resulting table, indicating the alignment of the corresponding
columns. Also, "" may be used to produce vertical lines
between columns in LaTeX tables, but these are effectively ignored
when considering the required length of the supplied vector. If a
character vector of length one is supplied, it is split as
strsplit(align, "")[[1]] before processing. Since the row
names are printed in the first column, the length of align is
one greater than ncol(x) if x is a
data.frame . Use "l" , "r" , and "c" to
denote left, right, and center alignment, respectively. Use
"p{3cm}" etc. for a LaTeX column of the specified width. For
HTML output the "p" alignment is interpreted as "l" ,
ignoring the width request. Default depends on the class of
x .

digits 
Numeric vector of length equal to one (in which case it
will be replicated as necessary) or to the number of columns of the
resulting table or matrix of the same size as the resulting
table, indicating the number of digits to display in the
corresponding columns. Since the row names are printed in the first
column, the length of the vector digits or the number of
columns of the matrix digits is one greater than
ncol(x) if x is a data.frame . Default depends
on the class of x . If values of digits are negative,
the corresponding values of x are displayed in scientific
format with abs(digits) digits.

display 
Character vector of length equal to the number of columns of the
resulting table, indicating the format for the corresponding columns.
Since the row names are printed in the first column, the length of
display is one greater than ncol(x) if x is a
data.frame . These values are passed to the formatC
function. Use "d" (for integers), "f" , "e" ,
"E" , "g" , "G" , "fg" (for reals), or
"s" (for strings). "f" gives numbers in the usual
xxx.xxx format; "e" and "E" give
n.ddde+nn or n.dddE+nn (scientific format); "g"
and "G" put x[i] into scientific format only if it
saves space to do so. "fg" uses fixed format as "f" ,
but digits as number of significant digits. Note that
this can lead to quite long result strings. Default depends on the
class of x .

auto 
Logical, indicating whether to apply automatic format when no value
is passed to align , digits , or display . This
‘autoformat’ (based on xalign , xdigits , and
xdisplay ) can be useful to quickly format a typical
matrix or data.frame . Default value is FALSE .

... 
Additional arguments. (Currently ignored.)

This function is only usable for production of LaTeX documents, not
HTML.
Creates an object of class
c("xtableMatharray","xtable","data.frame")
, to ensure that it is
printed by the print method print.xtableMatharray
.
An object of class c("xtableMatharray","xtable","data.frame")
.
