Create a simple table via kable with row groups and rownames similar to those of latex from the Hmisc package or htmlTable from the htmlTable package.

Usage

qable(
  x,
  rtitle = "",
  rgroup = numeric(0),
  rnames = rownames(x),
  cnames = colnames(x),
  markup = getOption("qwraps2_markup", "latex"),
  kable_args = list(),
  ...
)

Arguments

x

matrix or data.frame to be turned into a qable

rtitle

a row grouping title. See Details.

rgroup

a named numeric vector with the name of the row group and the number of rows within the group. sum(rowgroup) == nrow(x).

rnames

a character vector of the row names

cnames

column names

markup

the markup language to use expected to be either "markdown" or "latex"

kable_args

a list of named arguments to send to kable. See Details.

...

pass through

Value

qable returns a qwraps2_qable object that is just a character matrix with some additional attributes and the print method returns, invisibly, the object passed to print.

Details

rtitle can be used to add a title to the column constructed by the rgroup and rnames. The basic layout of a table generated by qable is:

rtitlecnames[1]cnames[2]
rgroup[1]
rnames[1]x[1, 1]x[1, 2]
rnames[2]x[2, 1]x[2, 2]
rnames[3]x[3, 1]x[3, 2]
rgroup[2]
rnames[4]x[4, 1]x[4, 1]
rnames[5]x[5, 1]x[5, 1]

Passing arguments to link[knitr]{kable} is done via the list kable_args. This is an improvement in 0.6.0 to address arguments with different use between qable and kable but the same name, notably format. Within the print method for qwraps2_qable objects, some default arguments for knitr::kable are created.

Defaults if the named element of kable_args is missing: kable_args$format will be "latex" if markup = "latex" and will be "pipe" if markup = "markdown".

kable_args$escape = !(markup = "latex")

kable_args$row.names defaults to FALSE

kable_args$col.names defaults to colnames(x)

See also

kable

summary_table, for an example of build a data summary table.

For more detail on arguments you can pass via kable_args look at the non-exported functions form the knitr package knitr:::kable_latex, knitr:::kable_markdown, or others.
