Functions related to table options.

Usage

find_posOption(table)

posOption(table)

posOption(table, asis = FALSE) <- value

find_widthOption(table)

widthOption(table)

widthOption(table, asis = FALSE) <- value

find_columnOptions(table)

columnOptions(table)

columnOptions(table, asis = FALSE) <- value

Arguments

table: A known tabular-like environment object, or the contents of one.
asis: Whether to make small modifications in replacement functions.
value: A character string or LaTeX2 object.

Value

find_posOption() returns the indices of the entries corresponding to the "pos" option, including the brackets, within the table.

posOption() returns a LaTeX2 object containing the "pos" option.

find_widthOption() returns the index of the block corresponding to the "width" option, if there is one. Only some tabular-like environments have these.

widthOption() returns a LaTeX2 object containing the "width" option, if the table has one.

find_columnOptions() returns the index of the block corresponding to the column spec.

columnOptions() returns a LaTeX2 object containing the "column" options.

Details

Unless asis == TRUE, the value for value in posOption(table) <- value can be specified with or without the enclosing brackets.
