Using response plot

In teal.modules.general: General Modules for 'teal' Applications

teal application to use response plot with various datasets types

This 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():

1. Load libraries
2. Create data sets
3. Create an app variable
4. Run the app

1 - Load libraries

library(teal.modules.general) # used to create the app
library(dplyr) # used to modify data sets

2 - Create data sets

Inside this app 4 datasets will be used

1. ADSL A wide data set with subject data
2. ADRS A long data set with response data for subjects at different time points of the study
3. ADTTE A long data set with time to event data
4. ADLB A long data set with lab measurements for each subject

data <- teal_data()
data <- within(data, {
  ADSL <- teal.data::rADSL %>%
    mutate(TRTDUR = round(as.numeric(TRTEDTM - TRTSDTM), 1))
  ADRS <- teal.data::rADRS
  ADTTE <- teal.data::rADTTE
  ADLB <- teal.data::rADLB %>%
    mutate(CHGC = as.factor(case_when(
      CHG < 1 ~ "N",
      CHG > 1 ~ "P",
      TRUE ~ "-"
    )))
})
join_keys(data) <- default_cdisc_join_keys[names(data)]

3 - Create an app variable

This 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.

# initialize the app

      mod4,
      mod5,
      mod6
    )
  )
)

4 - Run the app

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.

shinyApp(app$ui, app$server, options = list(height = 1024, width = 1024))

5 - Try it out in Shinylive

code <- paste0(c(
  knitr::knit_code$get("library"),
  knitr::knit_code$get("data"),
  knitr::knit_code$get("app"),
  knitr::knit_code$get("shinyapp")
), collapse = "\n")

url <- roxy.shinylive::create_shinylive_url(code)
cat(sprintf("[Open in Shinylive](%s)\n\n", url))

knitr::include_url(url, height = "800px")
