PlusMinus

Generate x +/- y terms in table.

This function generates a component of a table formula to output two columns separated by a +/- sign. It is designed only for LaTeX output.

PlusMinus(x, y, head, xhead, yhead, digits = 2, 
          character.only = FALSE, ...)

`x,y`	Expressions to be displayed in the columns on the left and right of the `+/-` sign, respectively.
`head`	If not missing, this will be used as a column heading for the two columns.
`xhead, yhead`	If not missing, these will be used as individual column headings.
`digits, ...`	Parameters to pass to the `format` function.
`character.only`	If `TRUE`, the `head`, `xhead` and `yhead` arguments will be interpreted as expressions evaluating to character values.

An expression which will produce the requested output in LaTeX.

stderr <- function(x) sd(x)/sqrt(length(x))
toLatex( tabular( (Species+1) ~ Sepal.Length*
          PlusMinus(mean, stderr, digits=1), data=iris ) )
