teal
application to use response plot with various
datasets typesThis vignette will guide you through the four parts to create a
teal
application using various types of datasets using the
response plot module tm_g_response()
:
app
variableInside this app 4 datasets will be used
ADSL
A wide data set with subject dataADRS
A long data set with response data for subjects at
different time points of the studyADTTE
A long data set with time to event dataADLB
A long data set with lab measurements for each

app
variableThis is the most important section. We will use the
teal::init()
function to create an app. The data will be
handed over using teal.data::teal_data()
. The app itself
will be constructed by multiple calls of tm_g_response()
using different combinations of data sets.

A simple shiny::shinyApp()
call will let you run the
app. Note that app is only displayed when running this code inside an
R
session.
