Use cases

Initially please make sure the course_data_dir and course_data_url variables are set:

course_data_dir = "./myEMURdata" # change to valid dir path on your system
course_data_url = "http://www.phonetik.uni-muenchen.de/~jmh/lehre/Rdf"

All the Q & A’s are based on the ae_emuDB that comes with the emuR package:

library(emuR)
create_emuRdemoData(course_data_dir)
db = load_emuDB(file.path(course_data_dir, "emuR_demoData", "ae_emuDB"),
                verbose = F)

You will need the following R packages:

library(emuR)
library(tidyverse) # this includes dplyr and ggplot2

Q & A’s

Please place your answers in the R Markdown code blocks or write the answers next to the A:
