It helps me understand by pointing out the problems and why it doesn't work.

I learned a lot about R.

great!

Please explain it to me easily.

I didn't know there were so many data visualization methods. You explained it in an easy and simple way, so I understood it quickly.

It was nice to be able to see examples of not only basic Excel charts but also applied charts. However, it was unfortunate that there was some noise in the voice, which was annoying, and that the last part of the lecture was skipped without finishing.

That's great

It was a good lecture.

I heard it well

It's easy if you think it's easy, but it's different when you make others understand it haha
