kable

From knitr v1.1 by Yihui Xie

Create tables in LaTeX, HTML, Markdown and reStructuredText

This is a very simple table generator. It is simple by design. It is not intended to replace any other R packages for making tables.

Usage

kable(x, format, digits = getOption("digits"), row.names = NA, col.names = colnames(x), 
    align, caption = NULL, escape = TRUE, ...)

Arguments

x: an R object (typically a matrix or data frame)
format: a character string; possible values are latex, html, markdown, pandoc, and rst; this will be automatically determined if the function is called within knitr; it can also be set in
digits: the maximum number of digits for numeric columns (passed to round()); it can also be a vector of length ncol(x) to set the number of digits for individual columns
row.names: a logical value indicating whether to include row names; by default, row names are included if rownames(x) is neither NULL nor identical to 1:nrow(x)
col.names: a character vector of column names to be used in the table
align: the alignment of columns: a character vector consisting of 'l' (left), 'c' (center) and/or 'r' (right); by default, numeric columns are right-aligned, and other columns are left-aligned; if align = NULL,
caption: the table caption
escape: escape special characters when producing HTML or LaTeX tables
...: other arguments (see examples)

Value

A character vector of the table source code.

Note

The tables for format = 'markdown' also work for Pandoc when the pipe_tables extension is enabled (this is the default behavior for Pandoc >= 1.10).

When using kable() as a top-level expression, you do not need to explicitly print() it due to R's automatic implicit printing. When it is wrapped inside other expressions (such as a for loop), you must explicitly print(kable(...)).

References

See https://github.com/yihui/knitr-examples/blob/master/091-knitr-table.Rnw for some examples in LaTeX, but they also apply to other document formats.

Examples

kable(head(iris), format = "latex")
kable(head(iris), format = "html")
kable(head(iris), format = "latex", caption = "Title of the table")
kable(head(iris), format = "html", caption = "Title of the table")
# use the booktabs package
kable(mtcars, format = "latex", booktabs = TRUE)
# use the longtable package
kable(matrix(1000, ncol = 5), format = "latex", digits = 2, longtable = TRUE)
# add some table attributes
kable(head(iris), format = "html", table.attr = "id="mytable"")
# reST output
kable(head(mtcars), format = "rst")
# no row names
kable(head(mtcars), format = "rst", row.names = FALSE)
# R Markdown/Github Markdown tables
kable(head(mtcars[, 1:5]), format = "markdown")
# no inner padding
kable(head(mtcars), format = "markdown", padding = 0)
# more padding
kable(head(mtcars), format = "markdown", padding = 2)
# Pandoc tables
kable(head(mtcars), format = "pandoc", caption = "Title of the table")
# save the value
x = kable(mtcars, format = "html")
cat(x, sep = "\n")
# can also set options(knitr.table.format = 'html') so that the output is HTML
