This vignette shows the general purpose and basic functionality of
the rlistings R package.
The rlistings R package contains value formatting and
ASCII rendering infrastructure for tables and listings useful for
clinical trials and other statistical analysis. The core functionality
is built on top of the formatters
package.
Some of the key features currently available to customize listings
created using the rlistings package include:
For information on listing column formatting see the Column Formatting vignette. To learn about listing pagination see the Pagination vignette.
The index of all available rlistings functions can be
found on the rlistings
website functions reference.
The rlistings package is intended for use in creating
simple one-dimensional listings. For construction of more complex tables
see the rtables
package.
With the basic framework provided in this package, a
data.frame object can be easily converted into a listing
using the as_listing function with several optional
customizations available.
A listing, at its core, is a set of observation-level data which is
to be rendered with particular formatting but without any sort of
aggregation or further analysis. In practice, this translates to to a
classed data.frame (or tbl_df) object with a
specialized print method. This means that, unlike tables created with
rlistings’ sibling package rtables, a listing
object is fundamentally the incoming data.frame with a few
annotations attached to it.
In the R code below we will give a basic example of how to create an
rlistings listing from a pre-processed data frame.
We first load in the rlistings package.
For the purpose of this example we will use the dummy ADAE dataset
provided within the formatters package as our data frame,
which consists of 48 columns of adverse event patient data, and one or
more rows per patient.
Now we will create our listing.
The df parameter sets our data.frame
object. The disp_cols argument takes a vector of names of
any columns taken from the data frame that should be included in the
listing. Column headers are set by the label attribute of
each given variable. If there is no label associated with a given
variable then the variable name will be taken as a header instead. For
this example we will choose 8 arbitrary columns to display - 5 specific
to the patient and 3 relating to the adverse event.
Since the dataset consists of 1934 rows in total, we will use the
head function to print only the first 15 rows of the
listing.
lsting <- as_listing(
df = adae,
disp_cols = c("USUBJID", "AETOXGR", "ARM", "AGE", "SEX", "RACE", "AEDECOD", "AESEV"),
)
head(lsting, 15)

associated with each patient, resulting in many instances of repeated
values over several columns. This can cleaned up by setting key columns
with the key_cols argument.
We can also declare the set of (non-key) display columns by
compliment, via the non_disp_col argument. If specifies
this argument accepts names of columns which will non be displayed. All
other non-key columns are then displayed.

Their core behavioral feature is that sequentially repeated values are not displayed when they do not add information.
In practice, this means that each value of a key column is printed only once per unique combination of values for all higher-priority (i.e., to the left of it) key columns (per page). Locations where a repeated value would have been printed within a key column for the same higher-priority-key combination on the same page are rendered as empty space. Note, determination of which elements to display within a key column at rendering is based on the underlying value; any non-default formatting applied to the column has no effect on this behavior.
The key_cols argument takes a vector of column names
identifying the key columns for the listing. A listing is always sorted
by its key columns (with order defining the sort precedence). Below we
specify trial arm and patient ID as key columns to improve
readability.
