The rtables
R package was designed to create and display complex
tables with R. The cells in an rtable
may contain any high-dimensional
data structure which can then be displayed with cell-specific formatting
instructions. Currently, rtables
can be outputted in ascii
html
,
and pdf
, as well Power Point (via conversion to flextable
objects).
rtf
support is in development and will be in a future release.
rtables
is developed and copy written by F. Hoffmann-La Roche
and it
is released open source under Apache License Version 2.
rtables
development is driven by the need to create regulatory ready
tables for health authority review. Some of the key requirements for
this undertaking are listed below:
CDISC
standardsrtables
currently covers virtually all of these requirements, and
further advances remain under active development.
rtables
is available on CRAN and you can install the latest released
version with:
install.packages("rtables")
or you can install the latest development version directly from GitHub with:
# install.packages("pak")
pak::pak("insightsengineering/rtables")
Packaged releases (both those on CRAN and those between official CRAN releases) can be found in the releases list.
To understand how to use this package, please refer to the Introduction
to
rtables
article, which provides multiple examples of code implementation.
We first demonstrate with a demographic table-like example and then show the creation of a more complex table.
