write.univ: Write Univariate Table to a File
In nutterb/lazyWeave: LaTeX Wrappers for R Users

Write the output of univ to a file

write.univ(x, round = 1, Factor = TRUE, Group = FALSE, N = TRUE,
  Missing = FALSE, Mean = TRUE, SD = TRUE, LCL = FALSE, UCL = FALSE,
  Min = TRUE, P25 = TRUE, Median = TRUE, P75 = TRUE, Max = TRUE,
  CV = FALSE, Pval = FALSE, pvalFormat = "default", pvalArgs = list(),
  cat = getOption("lazyWeave_cat"), ...)

`x`	An object of type `univ`.
`round`	Number of significant digits to be printed.
`Factor`	Determines if the Factor (variable) description is printed.
`Group`	Determines if the Group is printed
`N`	Determines if the number of non missing values is printed
`Missing`	Determines if the number of missing values is printed
`Mean`	Determines if the mean is printed
`SD`	Determines if the standard deviation is printed
`LCL`	Determines if the lower confidence limit is printed
`UCL`	Determines if the upper confidence limit is printed
`Min`	Determines if the minimum value is printed
`P25`	Determines if the 25th percentile is printed
`Median`	Determines if the median value is printed
`P75`	Determines if the 75th percentile is printed
`Max`	Determines if the maximum value is printed
`CV`	Determines if the coefficient of variation is printed
`Pval`	Determines if the p-value is printed
`pvalFormat`	Character string passed to `pvalString` and determines the pvalue style to be printed.
`pvalArgs`	A list of additional arguments to be passed to `pvalString`
`cat`	Logical. Determines if the output is returned as a character string or returned via the `cat` function (printed to console). The default value is set by `options()$lazyWeave_cat`. This argument allows for selective override of the default.
`...`	additional arguments to be passed to `lazy.matrix`

#to write univ based table to an HTML file enclose the

#see documentation for other options.

#To print byVariable group names in the table, 
#set the Group=T flag in the write.univ() function.
