This module analyzes missing data in data.frame
s to help users explore missing observations and
gain insights into the completeness of their data.
It is useful for clinical data analysis within the context of CDISC
standards and
adaptable for general data analysis purposes.
Usage
tm_missing_data(
label = "Missing data",
plot_height = c(600, 400, 5000),
plot_width = NULL,
parent_dataname = "ADSL",
ggtheme = c("classic", "gray", "bw", "linedraw", "light", "dark", "minimal", "void"),
ggplot2_args = list(`Combinations Hist` = teal.widgets::ggplot2_args(labs =
list(caption = NULL)), `Combinations Main` = teal.widgets::ggplot2_args(labs =
list(title = NULL))),
pre_output = NULL,
post_output = NULL
)
Arguments
- label
(
character(1)
) Label shown in the navigation item for the module or module group. Formodules()
defaults to"root"
. SeeDetails
.- plot_height
(
numeric
) optional, specifies the plot height as a three-element vector ofvalue
,min
, andmax
intended for use with a slider UI element.- plot_width
(
numeric
) optional, specifies the plot width as a three-element vector ofvalue
,min
, andmax
for a slider encoding the plot width.- parent_dataname
(
character(1)
) Specifies the parent dataset name. Default isADSL
forCDISC
data. If provided and exists, enables additional analysis "by subject". For non-CDISC
data, this parameter can be ignored.- ggtheme
(
character
) optional, specifies the defaultggplot2
theme for plots. Defaults toclassic
.- ggplot2_args
-
(
ggplot2_args
) optional, object created byteal.widgets::ggplot2_args()
with settings for all the plots or named list ofggplot2_args
objects for plot-specific settings. The argument is merged with options variableteal.ggplot2_args
and default module setup.List names should match the following:
c("default", "Summary Obs", "Summary Patients", "Combinations Main", "Combinations Hist", "By Subject")
.For more details see the vignette:
vignette("custom-ggplot2-arguments", package = "teal.widgets")
. - pre_output
(
shiny.tag
) optional, text or UI element to be displayed before the module's output, providing context or a title. with text placed before the output to put the output into context. For example a title.- post_output
(
shiny.tag
) optional, text or UI element to be displayed after the module's output, adding context or further instructions. Elements likeshiny::helpText()
are useful.
