## Program

Below is another complete example showing how the **reporter** package
can be used to create figures.  The example also shows how multiple 
pieces of content can be added to a single report.


```{r eval=FALSE, echo=TRUE}
library(tidyverse)
library(sassy)


# Prepare Log -------------------------------------------------------------


options("logr.autolog" = TRUE,
        "logr.notes" = FALSE)

# Get temp location for log and report output
tmp <- tempdir()

# Open log
lf <- log_open(file.path(tmp, "example4.log"))


# Load and Prepare Data ---------------------------------------------------

# Get path to sample data
pkg <- system.file("extdata", package = "reporter")

# Define data library
libname(sdtm, pkg, "csv", quiet = TRUE) 

# Loads data into workspace
lib_load(sdtm)

# Prepare data
dm_mod <- sdtm.DM %>% 
  select(USUBJID, SEX, AGE, ARM) %>% 
  filter(ARM != "SCREEN FAILURE") %>% 
  datastep({
    
    if (AGE >= 18 & AGE <= 24)

                                                          "25 to 44",
