Hi! @HScheiber

Thank you for inviting me on your GitHub. Here's my peer review for Homework 06. Hopefully you find these comments helpful!

Your repository is very organized. Your README file in your HW repository was easy to navigate with the links for each homework session. You organized your analysis with section headers, which made your code very clear and easy to follow. The table of links at the beginning of the assignment makes it easy to go to each section of the assignment. You demonstrated a good knowledge of coding syntax. You explained the code thoroughly so it is easy to understand your code.

Character data This part of the assignment was done well and easy to follow. You attempted all the exercises and provided a great answer for each of the questions. You explained your answer very well with adequate code and paragraphs. Great job!

Writing functions In this section, you wrote a function that take in a dataframe that contains an independent variable year, and output a quadratic fit of the chosen dependent variable vs year for every country. It is great that your designed your function that works for any country and any dependent variable such as lifeExp and gdpPercap. And you checked to make sure that the input must be a dataframe. You tried your function on both gapminder data and the data for Canada, and your ggplot of the fit looks great and certainly added more information about the data and the function.

Overall, this is a great assignment, I can't really think of any suggestions. Everything is clearly organized and well-explained :)

Hi,

Your repo is well organized and easy to navigate.

You had a very nice referenced list at the beginning of the homerowk 6 file. It’s a great idea and I will incorporate it in my assignments.

Character data You solved all the exercises and provided illustrative examples. Your job for this task was very good and I don´t have any suggestion for improvement.

Writing functions I llike that you checked that the input of your function is a data frame by using an if stop statement. I have never use this statement in R and is something that I’ll keep in mind for the future. I think that you’re coding was very well structured, organized, and properly commented.
