)

Arguments

exercise_text

Examples

exercise_code <- "
# Exercise: Calculate mean of mtcars$mpg
# TODO: Complete the line below
mean_mpg <- # YOUR CODE HERE
print(mean_mpg)
"

solution_code <- "
# Solution: Calculate mean of mtcars$mpg
mean_mpg <- mean(mtcars$mpg)
print(mean_mpg)
"

links <- webr_repl_exercise(exercise_code, solution_code, "basic_stats")
# Access with links$exercise and links$solution

# Custom path and version
links <- webr_repl_exercise(exercise_code, solution_code, "stats",
                          base_path = "/exercises/", version = "v0.5.4")
