7a. You left out a critical part. What do lines 4-8 do? Why are they important? 7b. There is a lot of code before the loop, 2 sections in fact, that you don't explain at all. 7c. I don't think we are completely understanding the same thing when I say segmenting procedure. Getting the midpoint, for example, is not segmentation. I am referring to how the textgrid separates elements in the recording. Consider how many scripts you used this week vs. last week. Do you recall any differences? What was the general strategy in PA2? What type and how many files did it produce? How is it different from PA3?
Regarding the descriptive statistics (question 10), using group_by(id) doesn't do anything because there is only 1 unique id (you). It would have been much more informative to group by language.
Nice job generating plots. You don't need to use another function call for ggtitle. You can add another argument to labs, e.g., labs(title = "title here"). Works either way! Again, nice job overall.
