pandoc.table.return
Create a table
Creates a Pandoc's markdown style table with optional caption and some other tweaks. See 'Details' below.
Usage
pandoc.table.return(t, caption, digits = panderOptions("digits"),
decimal.mark = panderOptions("decimal.mark"),
big.mark = panderOptions("big.mark"), round = panderOptions("round"),
missing = panderOptions("missing"), justify, style = c("multiline",
"grid", "simple", "rmarkdown", "jira"),
split.tables = panderOptions("table.split.table"),
split.cells = panderOptions("table.split.cells"),
keep.trailing.zeros = panderOptions("keep.trailing.zeros"),
keep.line.breaks = panderOptions("keep.line.breaks"),
plain.ascii = panderOptions("plain.ascii"),
use.hyphening = panderOptions("use.hyphening"), row.names, col.names,
emphasize.rownames = panderOptions("table.emphasize.rownames"),
emphasize.rows, emphasize.cols, emphasize.cells, emphasize.strong.rows,
emphasize.strong.cols, emphasize.strong.cells, emphasize.italics.rows,
emphasize.italics.cols, emphasize.italics.cells, emphasize.verbatim.rows,
emphasize.verbatim.cols, emphasize.verbatim.cells, ...)
Arguments
- t
data frame, matrix or table
- caption
caption (string) to be shown under the table
- digits
passed to
format. Can be a vector specifying values for each column (has to be the same length as number of columns).- decimal.mark
passed to
format- big.mark
passed to
format- round
passed to
round. Can be a vector specifying values for each column (has to be the same length as number of columns). Values for non-numeric columns will be disregarded.- missing
string to replace missing values
- justify
defines alignment in cells passed to
format. Can beleft,rightorcentre, which latter can be also spelled ascenter. Defaults tocentre. Can be abbreviated to a string consisting of the lettersl,candr(e.g. 'lcr' instead of c('left', 'centre', 'right').- style
which Pandoc style to use:
simple,multiline,gridorrmarkdown- split.tables
where to split wide tables to separate tables. The default value (
80) suggests the conventional number of characters used in a line, feel free to change (e.g. toInfto disable this feature) if you are not using a VT100 terminal any more :)- split.cells
where to split cells' text with line breaks. Default to
30, to disable set toInf. Can be also supplied as a vector, for each cell separately (if length(split.cells) == number of columns + 1, then first value in split.cells if for row names, and others are for columns). Supports relative (percentage) parameters in combination with split.tables.- keep.trailing.zeros
to show or remove trailing zeros in numbers on a column basis width
- keep.line.breaks
(default:
FALSE) if to keep or remove line breaks from cells in a table- plain.ascii
(default:
FALSE) if output should be in plain ascii (without markdown markup) or not- use.hyphening
boolean (default:
FALSE) if try to use hyphening when splitting large cells according to table.split.cells. Requires sylly.- row.names
if
FALSE, row names are suppressed. A character vector of row names can also be specified here. By default, row names are included ifrownames(t)is neitherNULLnor identical to1:nrow(x)- col.names
a character vector of column names to be used in the table
- emphasize.rownames
boolean (default:
TRUE) if row names should be highlighted- emphasize.rows

emphasize.italics.rowsbut in bold- emphasize.strong.cols

a vector for a two dimensional table specifying which rows to emphasize
- emphasize.italics.cols
a vector for a two dimensional table specifying which cols to emphasize
- emphasize.italics.cells
a vector for one-dimensional tables or a matrix like structure with two columns for row and column indexes to be emphasized in two dimensional tables. See e.g.

Details
This function takes any tabular data as its first argument and will try to make it pretty like: rounding and applying digits and custom decimal.mark to numbers, auto-recognizing if row names should be included, setting alignment of cells and dropping trailing zeros by default.
pandoc.table also tries to split large cells with line breaks or even the whole table to separate parts on demand. Other arguments lets the use to highlight some rows/cells/cells in the table with italic or bold text style.
For more details please see the parameters above and passed arguments of panderOptions.
Value
By default this function outputs (see: cat) the result. If you would want to catch the result instead, then call pandoc.table.return instead.
Note
If caption is missing, then the value is first checked in t object's caption attribute and if not found in an internal buffer set by link{set.caption}. justify parameter works similarly, see set.alignment for details.
